Just to let you know - after one week pf having Gabi on Royal Canin Yorkie ONLY, her itching/scratching has all but stopped.

I also put a cotton vest on her so that she did nod do any more dmae to her coat

Gabi says a big thank you for the sound advice
By the way - I'd LOVE to post photo's but have no idea how to do it?? Any advice is welcome!!
