Hello,
I’m sorry to hear about your dog. This is a complicated and difficult disease to manage. Please try to find a vet you trust who will help you manage this. Involuntary movement may or may not be indicative of improvement. So I don’t want to provide a false sense of hope. Be diligent with follow ups and know it is a process that takes time and patience. There is a lot of information at my blog and YouTube channel on this.
I wish you the best of luck.
Hello,
I’m sorry but this needs to be addressed by a vet who can examine your dog. There are too many unanswered medical issues here to guess at. I don’t know what the lumps are or how they might be related to the gi issues. Or if the medications alone caused them. At minimum a thorough exam needs be done. And then an aspirate or biopsy of the masses. This may require more than one visit so it is important to find a general practitioner vet to help with the process. An er is not appropriate for this as they are often to expensive and do not have the ability to make follow up appointments to help with the long term treatment plan. For a local vet you like and trust. They can help you and your dog.
