my rottweilers' head and back hair.
I have a rottweiler puppy of 4 months (female) her muzzle seems a little too pointy and her head seems a little small for her body and not boxy. Will her head fill out and get bigger???
Also, the hair on her back is thick and wavy..... will this go away??
She looks like a beautiful girl to me. Not all Rottweilers look the same, and the shape of their head or muzzle, size of their bone structure, coat density etc., are genetic traits. It's their bloodlines and parents, grandparents, great-grandparents etc. who have determined what those things will be like.
Although the Rottweiler Breed Standard describes the 'ideal' Rottie, the majority of them (even show dogs) won't be an exact replica of that ideal.
Rotties are slow to mature and generally don't get their full bone structure, height and weight until they're around 2 years old, or more. Your girl will 'fill out' as she grows, but there are no guarantees as to how big her head will get or anything like that. Feed her the best quality puppy food so that she gets all the nutrients she needs to reach her full potential, and keep her healthy, and she'll grow into a beautiful dog I'm sure.
As for her coat, some bloodlines have thicker coats than others, and puppies often have a wave down the center of their backs. This usually disappears as they get older and their adult coat comes in. However, unless your dog is a show dog it really doesn't matter, it's just cosmetic.
Hope this helps, best of luck with your girl.
