Hello all,New to the forum and new to the goldendoodle but we have a 4.5 month old girl we really enjoy. Recently we noticed a patch of shorter hair on her. Originally we thought it might be the topic flea tick liquid and a reaction but the vet says she’s never seen that without the skin also being infected. We thought maybe she was scratching it but I’m pretty sure her legs can reach top of her back. Wondering if she rubbed it on something also but we’ve never witnessed it. She doesn’t wear a harness. Anyone come across this before. Couple photos below as you will see it’s quite shorter in a ‘band’ across her back. Thanks!
