Donna- a number of things or situations can be the cause. It's difficult to diagnose without seeing the pet in person. We encourage you to visit your primary veterinarian during the daytime- if needed they can refer you to Upstate Vet. Otherwise, you're always welcome to come in through our Emergency Care department night/weekends/holidays.
Never trust the public for your dog's health. You should schedule an appointment to get him checked out.
