changing of the weather from going from tha a/c to outside in the heat. you nead a special comb that gets the under coat of a long haired dog brushed out during the summer months. i have the same problem with my little dog and her hair is not that long but she sheds real bad during the summer and she is an inside dog and i have to brush her every day and she still sheds. but check with your vet just to be sure.
