Hey-Just thought I'd mention it to you (because I always forget!) that most doggy day cares require up to date (as in, within the past 6 months) bordatella vaccines. I know you said your family never sends the dogs to daycare, so I thought it was worth mentioning. I don't get my dogs vaccinated for bordatella unless I know they'll be kenneled. All other shots are up to date though.
Just a thought. Hope it helps.
