I empathise with the difficulties of changing a dog’s diet. Mine both have digestive issues due to their breed.
Fortunately, my boy didn’t end up with a tumour. It was one of those situations where the vet suggested he’s either got cancer or he’ll be fine in a couple of weeks because the lump is an allergic reaction. I was lucky it was a result of an allergic reaction.
Good luck with the infrared treatments and training! I hope it helps your dog.
