Tolerance

"Tolerance, in a vet's mouth, means that a medicine has stopped working. It doesn't mean resilience. The owner hears the other meaning anyway."

The drive to the vet took five minutes and felt longer. I took the turn out of our street too slowly, the whole car seeming to carry something that could break, and I sat through a full cycle at the Yorktown Road lights before I noticed the arrow had come and gone. Millie was asleep on the passenger seat. The blanket I had arranged around her had slipped forward of her shoulders, and the heater was fogging a small pale circle on the inside of the window at the level of her nose.

The car park at Craigmore Village was half-empty in the way it was always half-empty on a Tuesday afternoon — the morning shoppers were gone, the school-run rush had not yet started, and the strip of shops sat in the pale winter sun with the look of a place running at half-attention. I pulled into a bay close to the clinic — not strictly a bay, more a hatched loading zone by the chemist's delivery entrance, but near enough to the door that I did not have to think about the distance — and killed the engine. For a moment I sat there with my hands on the wheel and let the fact of where I was arrive.

Lifting her out took longer than it should have. My bad arm objected to the chest-take and I had to swap my grip mid-lift, cradling her front half against my shoulder and using my hip to push the passenger door shut behind me. The dressing felt wet under the gauze by the time I had her balanced. I did not stop to check. The door of the clinic groaned open as I approached, and a woman coming out with a terrier stepped aside without a word — one of the small unconscious courtesies of the animal-owning world, the quick visual assessment, the instant ceding of right-of-way.

Inside, the clinic was mid-afternoon busy. Tuesday was surgery day, which meant the waiting room carried a different mix than I was more used to — fewer walk-ins, more scheduled pickups, the particular quiet worry of owners waiting for post-operative updates. The aquarium bubbled in its corner. A boxer was asleep under one of the scuffed chairs. The gardening magazines on the low table had not moved, as far as I could tell, since my last visit three weeks earlier.

Ava was behind the counter. She was on the phone, her free hand pinning a stack of appointment cards in place against the draft from the front door, and she was saying yes, but the point is we don't have him on file in a voice whose patience had been worn to the width of a wire.

She looked up when the door closed behind me. Her eyes went to Millie — to Millie's limp head over my shoulder, to the white of the exposed underbelly where the blanket had slipped away, to the way I was carrying her — and I watched something recalibrate in Ava's face in the space of maybe two seconds. Not the seasoned front-desk competence she had been building across her first winter at the clinic, but the younger layer under that competence, reaching for the training the moment needed. She cut the phone call short.

"Hang on, Mrs Pennock, I'm going to have to ring you back. Yes. Ten minutes." She dropped the receiver back in the cradle with a small clatter and came around the counter. She looked at Millie, not at me.

"Seizure?"

"Nearly two minutes. Post's bad."

"Put her on the couch." She gestured at the long low bench seat along the opposite wall that served as overflow seating on the busy days. "I'll get Karen."

I lowered Millie onto the bench. She did not stir. The owner of the boxer under the window had turned to watch us with the quiet attentiveness of someone who had read the situation accurately and was trying not to intrude on it. I did not have the attention to spare for her. Ava had already gone through the door that led to the back corridor, and I could hear her voice in a room somewhere behind the reception — low, quick, not panicked, not calm.

Karen came out ahead of her. She was drying her hands on a piece of blue absorbent paper and assessing Millie before she had crossed the length of the waiting room.

"Jerome. How long?"

"Nearly two. Long post-ictal. She didn't recognise me."

"When?"

"Half past two. Studying at my desk, she was asleep underneath."

Karen nodded without looking up. Her hand had settled on Millie's ribs to count the breathing, and her fingers had found the pulse at the inside of the back leg without having to look for it. She stood like that for a long moment. Then she straightened.

"Dr Turner's finishing a spey. He's twenty minutes off. We'll get her in the moment he's out. Is she drinking?"

"Not since it happened."

"Eaten today?"

"Half a bowl at breakfast."

Karen nodded again, this time at Ava rather than at me. "Pull the Smith file. Get the last phenobarb dose. I want the sheet ready for him when he comes out. Put her in Consult Two, rug her with one of ours, leave the door open."

Consult Two was the smallest of the three consult rooms and the one furthest back, which was why it doubled as a triage holding space when the front two rooms were booked — the quietest and the closest to the kennelling area behind. The examination table was stainless steel. The walls were the same off-white as the rest of the clinic. The fluorescent ceiling fixture buzzed faintly. The lower section of one wall had been fitted with a long low padded bench, softer than the table and better suited for dogs who were too ill to stand, and I had helped lay other people's dogs on it before, on the days when I had come in for Millie's routine appointments and had been asked to hold someone else's animal while the nurses ran to another emergency.

I lifted Millie onto the bench. Karen came in behind me with a folded tartan blanket that smelled faintly of washing powder and of whichever previous patient had last used it, and she laid it carefully over Millie's body.

"Rug her up. You know how they get."

"I know."

She paused at the door on her way out. "You haven't slept."

"Not really."

"Arm?"

"Slow."

"I'll get you a coffee."

"I'm alright."

"You'll have a coffee," she said, and shut the door.

Twenty minutes became thirty. I did not mind. Millie was warm under the blanket, her breathing steady though not yet entirely normal, and the door of the consult room had been left open to the corridor so that someone from the clinic passed every few minutes and glanced in. Sophie put her head in once to say Turner was nearly out and that Karen had not forgotten about the coffee. I thanked her. I sat on the low stool by the bench and kept one hand on Millie's back, so that when she shifted or twitched in her half-sleep I would feel it in my palm before I registered it anywhere else.

At some point across those thirty minutes I rang Mum. The call was brief. She asked me if I had eaten. I said no. She asked me again. I told her there was a stale packet of cashews in the glove box and I would eat them when I got back to the car. After she hung up I realised there were, in fact, cashews in the glove box — Charles had left them there two weekends ago — and that I would now have to eat them, because the alternative was to be a person who had lied to his mother, and I was not willing to be that.

The coffee arrived before the vet did. Karen set a chipped mug on the bench beside me and left without speaking. I didn’t drink it.

Turner came into the consult room thirty-five minutes from when I had walked into the clinic.

He looked tired. He was always a little tired — it was one of the steady features of the man, like the grey through the brown of his hair or the particular way he always seemed to have just finished washing his hands — but this afternoon the tiredness had a different register, the kind that settled across a day that had run its practitioner harder than he had planned for. He was still in scrubs from the spey. The scrub top carried a small brown smear on the hem that he had not noticed and that I decided not to mention.

"Jerome. Sorry I'm late."

He always said this. He was always late. He meant it every time, and everyone who came through his door had made a private decision either to accept the apology or not, and most had accepted.

He crossed to Millie and rested his hand on her flank, registering the warmth and the breathing before he said anything else. Then he turned to me.

"Walk me through it."

I did. I gave him the sequence I had given Karen. The desk, the Bach, Millie under the desk, the whine. The tonic phase, the clonic phase, the count. One minute fifty-one. The post-ictal.

"Tell me about the post-ictal in detail."

"She didn't recognise me. Walked into the desk leg. Lead clip didn't register. Three or four steps into the open space of the room, head down, not tracking. Took another minute or two before she'd respond to her name, and even then she was vague. I gave it ten minutes more and decided I needed to bring her in."

He had listened to this without taking a note. He took one now, on a sheet that Karen had pre-placed on the bench — the Smith file folder with Millie's history, open to the seizure log we had been keeping since February.

"Phenobarb this morning?"

"Eight. Sixty milligrams."

"When did she eat?"

"Around nine. She ate half the bowl."

"Any vomiting in the twenty-four hours before?"

"No."

"Any change in her generally? Fatigue different from usual? Drinking more, drinking less? Ataxia settling or not settling?"

"She's been drinking more. I noticed it a fortnight ago. Put it down to the weather turning."

He noted this too, with the small private nod that had always, in my observation of him across the last six months, meant that a datum had landed in the right slot and he would come back to it.

He stood and worked through the examination while we talked — the heart, the lungs, the lymph nodes, the gums, the capillary refill, the abdomen, the reflexes. Millie tolerated all of it with the weary flatness of a dog who had been examined too many times to object. She was still under. Her pupils were equal. Her third eyelid had partially come up on the right, which I noticed as Turner was noticing it, and we both said partial membrana nictitans at approximately the same moment. He granted me a small flat smile.

"Not a diagnostic finding in isolation. But noted."

"I know."

"I know you know."

He finished the examination, sat down on the stool across from me, and put the clipboard on his lap. He spent a moment with his pen at the top of the page before he started speaking.

"I'm going to draw bloods today. Phenobarb trough, CBC, biochem. I want to know where her serum level is sitting. She's been on sixty milligrams twice daily for five months. If the blood work shows the level has fallen — which, given her size and what you've described about the drinking, I suspect it will have — then what we're looking at is hepatic induction. Her liver's metabolising the phenobarb more aggressively than when we started her on it. The dose she's receiving is effectively less than it was six months ago."

"Tolerance."

"Tolerance is the word we use for it. Technically it's enzyme induction, but it amounts to the same thing clinically."

"What do we do."

"Three options. One: increase the phenobarb and monitor for side effects — ataxia, sedation, any signs the liver's starting to object. Two: add a second anticonvulsant alongside the phenobarb. Potassium bromide is the usual choice, cheap, works reasonably well in polytherapy, slow to reach steady state and hard on the stomach initially. Three: swap her off phenobarb onto a newer drug — levetiracetam would be my preference, cleaner profile, faster onset, more expensive, needs dosing three times a day."

"Which one?"

"My instinct is to add KBr. I'd rather not pull her off a medication that has worked for six months without knowing why it's stopped working, and increasing the phenobarb alone carries a liver risk I'm not keen on in a dog her age. But I want the bloods back before I commit."

I nodded.

He put the pen down on the clipboard. Then he looked at me across the bench.

"The other thing I want to do is keep her here overnight."

I had half-expected this from the moment Karen had put me in Consult Two, but the hearing of it still did something to my breathing.

"Tell me why."

"Seizure just under two minutes, post-ictal significantly longer than her baseline, serum level probably subtherapeutic. The odds of another episode in the next twelve to twenty-four hours aren't insignificant. I want her on a drip overnight with a diazepam line set up, so that if she goes into anything I can stop it before it establishes. And I want to draw the morning bloods here so we're not chasing her around the house if the levels are sitting wrong."

"She's never stayed overnight."

"I know."

I looked at Millie. She was asleep properly now, her flank rising and falling in the slow rhythm that meant she had dropped into the deep post-ictal recovery sleep that always followed an episode. Her head was turned against the blanket. The white blaze on her nose was half-hidden under the tartan. She looked smaller than she usually looked, in the way that sleeping animals always do, and I understood in that moment the weight of what Turner was asking: this was not a consultation I was going to leave with her beside me.

"I'll be honest with you, Jerome." His voice had shifted — not softer, but steadier. "I wouldn't keep her if I didn't think it was the right call. If you want a second opinion, I can ring Peter Hindmarsh at the university clinic and have him come through."

"No. If you're saying keep her, keep her."

He nodded, once. He did not offer the hand-on-shoulder reassurance that in another version of this consultation he might have offered. He picked up the pen and wrote the admission order.

"Karen will take the bloods in a few minutes. Sophie's on overnight; she'll check her every two hours and sit with her through the worst of it if anything starts. I'll be back in the morning from seven. You can ring any time — ask whoever picks up to put you through to the kennelling room. We'll ring you the moment anything changes." He paused. "She'll be in good hands."

I nodded. I did not trust my voice.

He stood. He put his hand briefly on Millie's head, as a vet and not as a man, and then he left the room, and the door closed behind him with the soft click that I had heard at the end of a hundred consultations across six months and had never, until that moment, noticed the particular sound of.
