Hello everyone..I have a five month old frenchie she has bad skin. She just wants to itch all the time. Right know I have a outfit on her so she will not itch so much. I have her on collegen from amzaon I give her that three time and day. Also Benadryl two time a day. I really don't want to give her the benadryl for ever. I know I have some people tell me it is her food. I feed her Royal Canin for puppys. I can not find one that is all beef for puppys. Can I give her adult food. Please help. I would put picture of her skin but I can't thru work computer.. Thanks
