hi
my mum has a yorkie/poodle, his coat was really thin, and so we clipped him really short and his coat is now thickening up. he is now on eukanuba and his coat is comming out lovely.
my kooikerhondje lost the slik on her coat, because i was bathing her too much (she kept rolling in poo), a breeder from sweden told me to put egg yolk in her food, it has come out really nice and especially now she is moulting, but i have had to cut her food down because it was making her put on weight.
your cavalier might have a thiroid inbalence and it is causing heim to have little coat, is it hard for him to put on and loose weight?
you could also use lintbells yeumega
