Quick history,
Archie is a 12 year old pointer cross who we rehomed about 2 months ago. When we first saw him he had a massive tumour on his leg (turned out to be a sarcoma) and lots of benign lumps all over the rest of him. When we first brought him home we thought he had kennel cough.
Since we've had him he's had new lumps appear (all benign so far, though there's one that came up yesterday). He has been being treated for kennel cough with two different types of antibiotic (one made no difference, one he had a bad reaction to), and a course of steroids (he got worse on the steroids).
The vet now says it's unlikely to be just kennel cough.
Archie's breathing has been getting more laboured, and sounds raspy. SO the vet prescribed some codeine.
We gave him the codeine this morning, mixed in with his breakfast. When we took him out for his walk, he was really unsteady on his feet and panting even harder than before.
We assumed it was a reaction to the codeine so have been making sure he drinks lots today, and letting him rest. Expecting him to feel better as the say wears on.
However he is now struggling to stand without leaning against something.
He's still eating and drinking as normal, but if we offer him a treat he will not try and get it (normally he goes mad for treats) unless you put it right in front of his mouth.
This isn't like him at all, he's normally very lively. He's not even trying to get up on "his" sofa. :(
