Spots on dog

Hi, Any idea what these spots could be on my golden retriever?

Hello - I'm afraid that I can't see this very well and from what I can see, there is a huge range of possibilities, from yeast infection secondary to dry or damaged skin, right through to (rarely) different types of cancer.  Your vet, who can see this in real-life, will be able to identify the most likely differentials (possible causes, or pathways of causes) and the best way to distinguish between them.  Until you know the most likely cause, it is difficult to suggest ways to treat, so if they are not sure or the skin doesn't respond to initial treatments, they may suggest further tests.  Finally, a lot of skin cases are chronic ie they respond to treatment but then recurr.  If this turns out to be the case, then chronic control- perhaps permanent or regular treatment of an underlying condition  - may be required.  It's easy to think that skin cases are 'only' skin deep, but sometimes they can be complex and can require a few appointments to get on top of.  Wishing you both the very best of luck from here - please will you let us know how you get on?
