Long snout v's short snout!!!
I have temporary custody of my sons rottie, Princess Jenna, while he proudly serves in the USMC...
Everywhere we go I get asked if she is mixed with german shepherd because she does not have the short snout, she was purchased as a pure breed and we have papers on her showing her lineage.
I see pictures all the time and not all appear to have the short snout but the question still comes up. Is it normal for them not to have the short snout?
Just because a dog is purebred, it doesn't mean it's going to look exactly like all the other dogs of the same breed. Bloodlines and genetics mean that there can be a lot of variety!
However, there is a Rottweiler Breed Standard which describes the 'ideal' Rottweiler. Generally the better the lineage of the dog, the closer it will be to this 'ideal' while allowing for individual breeders' preferences.
The muzzle should be fairly short, deep and wide. It shouldn't be like a 'hound' muzzle (long and narrow). It's a little difficult to describe in words, but the length of the muzzle should be roughly 40% of the total length from occiput (back of the head/skull) to nose.
Even if your sons' dogs' muzzle is narrow or longer than the 'ideal', it's a cosmetic issue and since she's not a show dog or being used to breed, it shouldn't matter one bit. Princess Jenna is no less special because of the shape of her muzzle.
Hope this helps. Best of luck with Princess Jenna and best wishes for your sons' safe return home.
