I got my dog from a BYB (I know bad choice). Shady deal, long story short she was probably only 4-5 weeks old-too soon to be away from the mom. Anyway, a week or so later I noticed a kink towards the end of her tail. I don't know if she came that way or if it happened rough housing with my cocker spaniel. The vet said she broke it some how but shouldn't be a problem or cause her pain. Is this true? Is there any way to correct it? Should I have it docked at the break or leave it? Shes 7 months now and an awesome dog. I don't want her in any unnecessary pain but it looks a little silly.
You can see it in this pic a little bit but that is from a month or two ago. Now its a 90* angle. Any advice?
