As many of you know my son works in an emergency Veterinary hospital,so the potential of all sorts of diseases coming in my home is present every day, I do take precausions, like you will notice a welcome mat in front of the property gate from the driveway, I spray it with a bleach solution every morning and every night, is a precaucion I must take because you never know what walks in the hospital and my son will drag it home. also I spray the mat when I am expecting company of any sort.. one visit I don't allow until the pups are 12 weeks is another dog since the dog can't step on the mat with bleach. I also mop my floors with a solution called
Chlorhexidine Disinfectant Solution which is the one used in vet hospitals to kill most diseases.
and in a nut shell that is how I keep my dogs healthy and my property protected.. for security, I have a BIG Alaskan malamute that protects the outside of the house and ADT protects the rest..
hugs,
