German Shepherd Bitch Stripe
I have a 4 month old male purebred German Shepherd pup and in the last month he has developed grey/silver hairs along his back and particularly around the top of his hips. I have now come to know this as a bitch stripe. I was just curious if this would go away as he got older? As he did previously get very very light at the base of his tail and we though it was going to go tan and continue down the rest of his tail but it then turned black again and has stayed black. Could this be a hormonal thing? His testicles havent dropped yet and we did some researching and found out that a bitch stripe is common in Bitches and neutered males. So we assume that when they do dropp(his testicles thatis) his hormones will then turn the hair back to black, would this be correct?
