Hi I'm new to YT so hope I'm posting in correct place. My yorkie is 6mths old and has scratched herself bald from her hind legs up to shoulders. We had a flea issue for a while despite monthly treatment. I finally realized the issue was outside then of course in my house. I treated my yard and house several times and started her on Program Plus rather than Front Line. The fleas are under control but it was almost like overnight I noticed she had lost a ton of hair. Will her hair grow back and if so how long will it take? I read on some sites that it could be permanent
