Separation anxiety is pretty common among pets. In fact between 20 to 40 percent of cats and dogs become anxious and display behaviours such as improper urination and defecation in the house, excessive barking, howling, and chewing.
Creating a routine can help your dog or cat to have a calmer and more predictable day whenever you are away.
Taking your dog for a walk or playing a game with your cat before you leave can help with energy release and a good nap!
Having your TV on or playing music, or audiobook can help your pets feel less alone.
Using puzzle feeders or hiding small portions of dry food around the house can keep your pet entertained.
Keep your farewells low-key to help them adjust to the new routine.
