Most Cavalier people will take a crate to all shows even if they only have one dog,
Depending on how far the car park is from the ring If it's a long way I take my dogs in the vrate on the wheeled base(easier than trying to carry everything)
I take my full grooming kit which contains my bait bag, poo bags, bushes, combs(scissors not usually required as you are only supposed to trim the under fur on cavaliers & this should be done at home but they are in there anyway),ring cllip, show lead & collar, rescue remedy etc
Bait is cooked chicken, water for the dogs
Dog first aid kit which is always in the car anyway
Would not suggest a benching chain for a cavalier
If you do not have a dry coat for your dog you should bath it a few days before the show to allow the coat to settle before the show then the night before just wash the whites & ears
Grooming tabls are the norm for Cavaliers
