Well, it is a broad question. Here is the thing. It is possible that there is an issue with the food itself, such as a) it might have rancid fats, b) it might contain something that doesn’t agree with your pup’s system … more importantly, your pup might not be feeling well. Here is how that works – some foods are more attractive/palatable than others and entice being eaten even if the stomach feels upset. For example, we had a similar problem with Jasmine (also since she was a pup) and eventually it turned out she had IBD.
I’d starting by having a close look at the food, followed by a vet evaluation. This might not be an easy thing to figure out but it is important that you do.
Hello,
I would suggest going to the vet for an exam. I would also expect that they can’t tell you exactly what’s going on without a biopsy of the masses. But it might help to reduce the chances of some of them being mammary tumors by spaying her. Good luck. Don’t lose sleep just head to the vet. I don’t think this is an emergency but try to go in the next few days. Let us know what they say.
