Are you going?
My fave vendors are Mistaken's Boutique for the
Portable Pet Water Bottle <-- best as its a no spill one and filtered. I love it. They also have some cute bow ties for the boys.
Dearmint - I love them for hair elastics, the softest beds. Last year we bought this car seat. We also bought this donut bed that is incredibly soft. Anyone who stays here tries to get into this bed first. This year, I am going to buy a bunch of these.
Then the next is Wheatley Wares and if you shop at his store, tell him I sent you as he knows what is good for havanese. I get my mixing bottles from him for shampoo and conditioner. I also get brushes, combs, scissors and much more. If you see anything on these sites you want them to bring to the show, let them know. They each bring a limited amount of things.
I get nothing for this. I am simply giving you a heads up of what I find to be good quality and useful.
