[Lucy's mom]

I try to brush Lucy's hair everyday and after I'm done brushing it, it looks so nice and silky. I use a spray in condition/detangler. However, shortly after I brush it, it's back to looking dull and matted. I put her on this pill (I don't remember the name of it but I got it at PetSmart, it's not missing link as I can't find missing link) that is suppose to help with making the coat shiney and silky. She has been on it for 2 weeks now and I have not noticed a change yet. I just recently switched her food to Innova-I think it is to soon to tell if this will help with her coat or not; I'll give it time though. Anyway, yesterday I put a really cute t-shirt on her for several hours and when I took it off she was completely matted, worst I've ever seen! Is anyone else experiencing hair that gets matted so fast and easily? If so, what are you doing to stop it??
