Noticed this "lump" on my 5.5 month old's GSD about a month ago. Showed it to my vet and he said not to worry about it unless more start showing up... which doesn't exactly provide an explanation...
I've been keeping an eye on it, and it seems like it has gotten a bit larger, more crust-like, and also lighter colour. It was previously dark grey, now it's looking lighter.
Snapped a few pics best I could:
Any ideas what this could be and what I should be doing about it? My vet is really proving to be rather useless, I'm looking for another one. If by some chance someone from Vancouver, Canada is reading this and can recommend one, I'm all ears!
