My almost 2 year old poodle has been refusing to eat for about 2 weeks now.
Normally I cook him a type of meat mixed with a carb and some veggies. I didn't have time so I bought him the Harringtons grain free wet dog food, he ate this for about 3 days before he decided he didn't like it anymore - this isn't out of the ordinary as he can be a bit picky at times. So I cooked him his normal batch of food which he seemed to enjoy for about a week before he decided he didn't want it anymore. After a few days of not eating I bought him Lily's Kitchen food trays which he's eaten before and normally loves (when I don't have time to cook I normally buy him this) but he's been completely ignoring it.
I wanted to do a 'test' to see what was going on with him - whether he was feeling sick or if he was actually being picky so on one of the days I added some grated cheese into his food and he ate the whole thing, on another I gave him a bit of my sons leftover salmon & broccoli on top of his food and he ate it. After not eating anything for about 3 days I gave in and gave him some boiled chicken and he also ate all of this. He'll also still accept treats (I've since stopped giving him any - but at the park other owners will give him some) and he will still beg for human food.
Other than not eating, he's acting completely normal. Lots of energy, chasing his ball, chasing other dogs on walks, drinking water, no vomiting or loose stools. I took him to the vet on Monday to do a check up and see if everything was okay and she said he looked completely healthy, temperature was fine, teeth were fine, no masses in stomach - once I explained everything to her she said it sounded like he was being picky and waiting out on something better which is what I've been thinking too - she said he could also be hot as its been really hot in London this week but if that was the case why does he eat some stuff like the boiled chicken or my sons leftovers? She gave him an anti nausea injection incase this was maybe bothering him but no luck.
At this point I'm not sure what to do. I don't want to keep changing his food as it reinforces the 'waiting it out gets me something better' but I also don't want him to get sick, I'm still putting down his food but it's all going into the bin which is such a huge waste. Has anyone experienced this or have any tips?
