Wasn't sure where to post this... So Callan had his first "groom" 2 weeks ago. My groomer commented on how much undercoat he had, given his age and time if year. And she is correct....he does have a lot, though still covered with puppy fluff....little guard hair yet. But a few days after his bath and brush out, I noticed a strip down his back about 2 inches wide and 4 inches long where there is very little undercoat. It looks like he has a reverse Mohawk! Poofy fur all around this one strip. And kinda bare down this strip. I assume this is normal, and maybe getting his first big boy bath while starting to transition from his puppy coat to adult is likely the cause? Thoughts?
