Health & Medical

The park looked normal that Tuesday. Then every third dog started coughing like it had a feather stuck in its throat. I counted four coughs in five minutes, all from different dogs, none of them mine, and I still went home and wiped Buster's paws like a nervous parent.

Canine influenza is a respiratory virus. Dogs catch it from each other the way kids swap colds at school. Vets say it spreads through the wet stuff, sneezes, the shared water bowl at agility class, a sniff of another dog's drool on the grass. It is not the human flu. You cannot catch it from your dog, which was the first thing I asked, because I am that kind of worrier.

Buster picked it up anyway. He was fine on the morning walk, then by evening he sounded hoarse, low on energy, with that cough that makes them gag a little at the end. He still wanted his dinner. Dogs with this bug usually do, and that is what fooled me into thinking it was nothing serious.

The vet was calm when I called. She said the usual advice is to watch for the red lines. Lethargy so deep he will not lift his head. Trouble breathing. A fever you can feel at the ears. Green or yellow snot instead of clear. Buster had none of that, just the cough and a sorry look, so we kept him home and let the virus run its course.

That course is rest and time. There is no pill that kills dog flu. Vets treat what they can see. Fluids if he will not drink. A cough suppressant if the coughing keeps him up at night. Antibiotics only if a second infection moves in, because the virus itself shrugs them off. The usual advice is supportive care, a gentle name for a lot of waiting and wiping snot off the floor.

We isolated him for a few weeks. No dog park, no play dates, no nose through the fence at the neighbours' lab. The virus sheds for a while even after they feel better, so sending a freshly recovered dog back is how the whole block gets it. I told the group chat. A few people groaned, but two of them had coughing dogs already, so it was fair warning.

The vaccine came up at the next visit. It exists, our vet said, but it is not on the core list like rabies or distemper. It is for at-risk dogs, boarders, show dogs, the ones who live at daycare. Buster is a couch philosopher, so we talked it through and decided on his real risk, not my anxiety. If your dog mixes with lots of others, talk to your vet about whether the shot fits yours.

What surprised me was how fast it moved. One sick dog at the park and within a fortnight half the regulars were coughing. Our vet said outbreaks sweep a community and then fade, which matched what I saw. By the time Buster was cleared, the coughing had mostly stopped, but I kept him on a long lead for a week, just in case.

He got his bounce back slowly. The first full-energy morning he chased a leaf for ten minutes and I nearly cried from relief. Most dogs, given rest and fluids and a human who watches the red lines, come through fine. If yours goes the other way, with heavy lethargy or struggling breath, that is the moment to call the clinic, not ride out the weekend. Our vet said the rare bad cases are the ones people try to sit out at home, and I have not forgotten it.

The shared bowl still bothers me. Someone always leaves a community water dish, and I am now the person who brings his own and pours it away after. Buster drinks, we leave, the next dog does not inherit his germs. The flu will come around again, the vet says it always does, but a little distance and a clean bowl slow it more than people think.

I washed his bedding twice and ran the vacuum over the sofa, though I am not sure the virus cares about tidy. The point was feeling like I was doing something. Our vet laughed when I told her and said the real control is keeping sick dogs home, not scrubbing the house. Easier said than done when your dog gives you the eyes at the door.

At the check-up the vet listened to his chest with the cold disc and said his lungs were clear, and that is what keeps most cases mild. She explained that dog flu mostly stays in the airways, not deep in the lungs, so the breathing watch matters more than the cough itself. The scary pneumonia version is rare, but it is the one to watch for, she said, which is the reason the breathing watch matters more than the cough alone.
