Being forewarned , you can get your pet to the vet quickly before the illness gets out of hand.

There are some pet owners who want to have their pets tested by the Orthopedic Foundation for Animals as well as the Canine Eye Registration Foundation to rule out health defects such as hip dysplasia and cataracts before they manifest themselves in their pets. This is of particular importance to breeders so as to prevent the parent dogs passing bad genetic conditions to the puppies.

Hip Dysplasia:

This is a common skeletal disease where the dog’s hip joints don’t develop properly. It can be terribly painful for your pet to get around. It’s a genetic condition and while it is more prevalent in big dogs, any breeds are susceptible.

Your dog will battle along with painful joints and sometimes his hind-end will be lame. You’ll notice that once lying down, he battles to get up again. Fortunately vets are well acquainted with this ailment and they have different options to treat and manage it.

Cataracts:

Cataracts in your dog come about from a disease process which affects the lens of the eye. The eye loses its transparency and impairs vision. There are some instances where cataracts can cause blindness. You’ll see a whitish gray area in your pets eye. The most common cause of cataracts is genetics. Get your pet to the vet who will do certain tests to evaluate the eyes and make a recommendation.

Treat your big Mastiff dog like the wonderful fur-child he is and make sure your attend to all his medical needs to avoid pain and discomfort for him.

Cherry Eye:

Cherry eye is a fairly common health issue with this breed. It affects the tear gland of the third eyelid, and if left untreated, can lead to ongoing eye problems.

All dogs have a third eyelid, as well as two tear producing glands to lubricate the eyes. Its an important protective component to eye health in dogs. When the connective tissue that holds the gland in place is damaged or weak, there is a red protrusion of the gland from the lower eye. This is a congenital disorder. Don’t ignore it, but get your pet to the vet so you can catch it early.

Bloat:

Canine bloat, known as gastric dilatation and volvulus can be a killer disease for your pet, more so with deep-chested, large breeds.

Gas accumulation is known as bloat, and its the accumulation of gas which can cause the stomach to rotate. A dog can go into shock from bloat. The reason for this is that the stomach expands, putting pressure on veins. Blood can’t flow as it should and the blood supply gets cut off to the stomach.

Your dog could be vomiting, restless, the stomach hard and bloated or he may be drooling. Dogs who gobble their food down and eat just one large meal a day have an increased susceptibility to GDV than other dogs.

The wrong ingredients of a dog’s diet can also contribute to bloat. High quality food and feeding your pet smaller meals can help.

As a working dog used to long hours of action, the Cao da Serra de Aires will need lots of activity. He’ll need you taking him for long walks and playing ball games with him. He can become frustrated and destructive when left without any physical stimulation.

Grooming

The Cao da Serra de Aires may have long hair but he isn’t high maintenance. He won’t require professional grooming, but will require a good brush a least twice a week. This is because the long coat can tangle.

To keep him looking his best, you’ll want to be trimming the hair around his paws. Another important grooming task is checking his ears and cleaning them. You have to be careful about cleaning your pet ears if you don’t know how, as it could damage the ears. Your vet can always advise you on how this is done.

Grooming:

A Korean Mastiff is an easy dog to groom with his short smooth coat. He is a moderate shedder so a brush twice a week will be sufficient to maintain the shiny, smooth condition of his coat.

Because the dog has lots of skin and folds, these folds will need to be washed and kept clean as grime can collect.

While you're busy attending to his skin check his nails too and check inside and outside his ears for signs of redness and irritation.

Diet:

Puppies use up more energy than mature adults, requiring a diet of good quality protein. Dogs that have been spayed or neutered will require less calories as will senior dogs.

Korean Mastiffs require high quality nutrition, and if its dry kibble, make sure its the best brand. Mix in some home-made food such as cooked chicken, brown rice and vegetables from time to time as well as some raw meat occasionally.

Protein and fat from good sources are top ingredients for your Korean Mastiff. Avoid food with allergens such as corn and wheat, sweeteners, preservatives and colorants.

Make sure your large pet has constant access to fresh water.
