The ideal time for your pup to wear a sweater is most likely when they need some extra warmth. Bigger pets can wear large dog sweaters, but they are sometimes less likely to need thick sweaters in colder temperatures, especially if they have a lot of fur. But toy or smaller breeds, older dogs and pups with thin coats may be more comfortable wearing sweaters for dogs than going without.
Some pups enjoy the comfort of dog sweaters and may feel great wearing them around the house. If your dog isn’t used to wearing clothing, make sure to reward them for accepting the sweaters and provide plenty of positive reinforcement.
