Deafness in Dogs:

A dog can lose it’s hearing because of an ear infection. That is why it is so important to watch your pets ears and make sure that the ears aren’t red and that your pet isn't continually scratching his ears.

The most common cause of congenital deafness with a dog is pigment-related. Dogs with white coats are often affected by deafness and you commonly see deafness in dogs with white pigmented skin because they carry the piebald gene – the white coat and often blue eyes. Without a particular stem cell, the white dog’s body isn’t able to make a special layer of hearing cells.

Hip Dysplasia:

Bloat for this dog can be life-threatening, and can often be because the dog is too hungry and he gobbles up his food quickly.

Rather give your dog two smaller meals – one in the morning and one in the evening, or even give several smaller portions throughout the day.
