Hi. I just purchased a female Dobe, 11 wks old, on friday. I noticed her left frontleg is knuckling, but only occasionally. I took her to the vet today and of course she wasnt doing it. The vet was rather rude and told me to get a video of it. As if! So Im going to get a 2nd opinion on friday ( in 2 days ) from a vet who has staff that have had dobes for years. Any insight on this is appreciated. Is it usually temperary? She also told me to put Snooki on large breed puppy, I thought that was inappropriate for Dobes? She's on Prairie now but Im thinking of switching to Canidae. Thanks in advance.
