Is your dog losing hair or itching uncontrollably with no signs of fleas? If so, your dog may have mange. Mange refers to a skin disease that is caused by parasitic mites. These mites are very tiny, and they can be dog-specific or can be zoonotic and infect other species, including humans.
An average of somewhere around 1 to 2 hours per day of exercise is right for the majority of dogs, but this varies between dogs. Variables such as breed, age, and overall health make it necessary to tailor an exercise program to your dog's specific needs.
If your dog has intestinal worms, then any of the worming treatments can be used. There is no worming treatment that is 100% effective. Heartworm is more challenging to treat. Killing the worms can cause even more inflammation in your dog's blood vessels, and his symptoms may worsen significantly. For this reason, treating them is a two-step process.
