The coats come with instructions basically you should towel your dog off & dry the dog's coat until it is just damp Then comb the dog's coat how you want it & then put the coat on. I used them on my Cavaliers who sleep on their backs, keeps the coat flat & you can keep it on until you are ready to get her ready for the ring, but a word of caution take her tail out of the coat part that covers it if she wants to toilet ! If you get a coat you will see why

Hi Shampoo well i use a pro-vitamin one that I got from Simpsons most of the time however if I think their whites are not as they should be I use Chris Christensen.White on White I only use conditioner if I think their coats are getting overly dry which isnt often but then I live in a soft water area and do think this makes a big diference.
The Johnsons Lavender and Camomile Baby Powder I just buy in the supermarket or chemist.
See you at Blackpool
