Periodontal Disease
Like most small breeds Italians are prone to infection in the gums known as gingivitis and also infection in the bone known as periodontal disease. Not only is this an unhealthy condition for the dog but it is also unpleasant for the humans around it!
Fortunately this is preventable with good diet and regular oral hygiene. It is easy to train a young puppy to have his teeth cleaned. Although it is not necessary to clean the milk teeth it is wise to get your puppy used to a tooth cleaning routine even at this tender age.
All that is necessary at this stage is to rub some tasty doggy toothpaste ( never use the human variety ) around his teeth and gums with your finger. Then encourage him to chew on a tooth brush (child size ) with some of the tasty paste on it! Gradually introduce him to gentle brushing and when his permanent teeth come through to firmer brushing. Circular movements are the best paying particular care to remove particles of food from around the gum margin.
Bleeding gums are a sign of infection and this means stepping up the routine to brushing every day. Your vet can advise you on other steps that may be necessary such as anti- bacterial toothpaste or professional scaling and polishing.

"What? Just because he's cross-eyed???"
"No, because he's really, really heavy
