My Aussie Has A Thin Coat
Hello! I have a 4 year old red tri Australian Shepherd. She was spayed at about 7 months old, before first heat. She was very fluffy and Aussie looking as a pup, but through maturity her "full" coat never grew in. I know she is purebred, as I received papers from the breeder, but as a companion dog, I never registered her.
Her coat is soft and wavy, but not thick or full bodied. She has never displayed any symptoms of skin disorders. She is extremely agile and leaps like a gazelle and flips in the air for tennis balls. She displays very strong herding instincts, and what I'm getting at is that she otherwise seems like a normal Aussie. Admittedly, she is also longer than most Aussies I have seen and more lanky, rather than stocky; very lean.
What could be the reason for her the reason for the shorter, thinner coat?
