How about doing research of your own? Find a low carb food and feed that. You’re dog will be more satiated and loose weight while keeping muscle. Vets usually don’t know much about nutrition unfortunately. The big three are all filled with carbs which will lead to weight gain in most dogs if not careful. As far as allergies go. My lab has seasonal allergies outside so I have to wipe his paws off and his lower belly if he walks in grass while outside. That helps a little but some of those allergies aren’t possible to completely get rid of.
