Remember that most of them have the same requirements of • Must be well socialized, • Must be spayed or neutered if over 6 months of age, • Must be current on all vaccinations including rabies, combination shot and bordetella, • Must have a recent fecal exam at your veterinarian to test for intestinal parasites,• Must be flea free, • Must be wearing a quick-release collar with some sort of name identification.
We live accross the water from Seattle in the Bremerton area and have never used these Kennels, but know what you are talking about when you say they are our babys. I know our 75 lbs Yellow Lab is my wife's baby, and it's hard when we have to board him. Good luck, and hope you have a great cruise.
