Pets can get stressed when their environment changes, which it often does during the holiday season when you have lots of family gatherings or unfamiliar guests in and out of your home for holiday get-togethers or even something as small as a change in their meal times or general schedule. I’ve seen first hand many little Chihuahuas just become a bundle or nerves when people are over (sure, this is not uncommon for a Chihuahua of course). Pet stress could also come from travel – i.e. long car rides, crate travel during flying – or from being left at home for longer periods of time while the family is traveling. Jack and Jill think that whever they get in the car, they’re going to the vet!!
