I have an 11 yr. old female with a furry coat, she's a red fawn and everyone has always remarked about how soft her coat is, but she has never had the shiny sleek coat that most non-fawns do. Anyway, she has been shedding an enormous amount of hair, piles of it, and even when I stop grooming her I could really keep going because it doesn't seem to stop coming out. Maybe this is normal for her but it doesn't seem to me to be normal for a greyhound. My vet thought she just might be shedding her summer coat. Has anyone had this problem before?
