How stringent should I be with requiring all dogs boarded at my home are up to speed with shots, annual fecal tests and flea and tick preventative?
I always ask for copy of vet records. Many times these don't include if dog is on flea/tick preventative and/or annual fecal test results.
I think you're doing the right think just by asking about all this to protect yourself, your family (including fur-kids), home, and know of the guest' status. If you have the vet information, you could probably check fecal results not on paperwork. With flea OTCs, I ask which one & take their word.
