My almost 6 month old puppy is having diarrhea. We changed his food about 2 weeks from Purina pro plan puppy to the purina pro plan large breed food. He is a lab/mastiff mix. Do you think it’s the food causing the diarrhea? Should I switched him back to the old stuff? Or give him more time? He is acting fine other then the diarrhea. Thanks!

My 6 yr old female Spaniel mix has a growth in her foot pad. It has gotten bigger recently but she has no issues running, it doesn’t seem to hurt her when I touch it, and she does not lick it. I have taken her to two vets, both have never seen anything like it and do not know what it is. They both suggested surgery for removal.
Do you know what this is? Are there any natural remedies I can do before considering surgery? Will it potentially come back after removal?

I have an 9 year old spayed female pit/terrier mix with a history of liver disease. She has recently been getting hairless black spots showing up on her sides and legs, especially in the rear. Her biopsy came back as possibly ischemic dermatomyosits. The antibiotic that her vet put her on seems to have made no difference, and the fish oil and vit E are A) difficult to give her and B) she hasn’t been on them long enough to know if they are helping. She has no apparent muscle involvement. Would doing blood studies for autoimmune diseases help me get a better plan for treatment? What specialist would be best to manage her care? Any information or help in this problem would really be appreciated!
