If you suspect that your dog is chuffing, try these tips: Look for signs that your dog is hungry, such as panting, drooling, or chewing on his paws. Make sure your dog has enough water to drink. Make sure she gets plenty of exercise, especially if she hasn’t been active lately. Talk to your vet if your dog isn’t chuffing after a few days of being inactive. Try giving your dog a treat every time she chuffs. Put your dog’s favorite toy in another room. Leave your dog alone until she stops chuffing.
