Cataracts:

Most older dogs have hardening of the lens and this is when the lens turns a whitish or greyish colour. However if your dog has cloudy eyes, it doesn’t simply mean he can’t see well as he often can. Once a lens has a cataract, some people try nutritional support of the lens which can work to lessen the severity of developing cataracts.

Surgery can help but a veterinary ophthalmologist can determine if cataract surgery is needed as most times it isn’t. If you can’t afford surgery, it is still important to have your dog evaluated by a veterinary ophthalmologist so that you avoid further complications with your pet’s eyes.

Progressive Retinal Atrophy is another eye disease, a degenerative disease that affects the photo-receptor cells where they deteriorate over time and can eventually lead to blindness in the affected dog.

Grooming:

The Gran Mastin de Borinquen, with his short coat, is a relatively low maintenance breed. Brush him at least twice a week to keep the coat free of loose hairs. Other grooming requirements are keeping his ears clean and dry. You can ask about alcohol wipes at your local pet shop to use in his ears. Check the nails too and remember to brush his teeth a couple of times a week to avoid dental decay.

Exercise:

You won't find the Gran Mastin de Borinquen being a particularly high energy dog but he also isn't a couch potato. If you enjoy a walk every day for your own good health, include him in these walks and give him a game of ball every now and again.

Diet:

This Mastiff -type dog is large, and they tend to be fairly lazy, not using up great deals of energy. Young dogs however use up more energy and will require a diet with good quality protein.

Dogs that have been spayed or neutered as well as senior dogs will require less calories. If you buy commercially manufactured food, check the labels carefully and buy high quality food for a large breed.

Don't just feed your Gran Mastin kibble everyday but alternate it sometimes, mixing in some raw meat into his kibble or mixing in some cooked chicken, rice and vegetables.

Grooming:

The Field Spaniel has medium-length to long hair and to avoid matting of the hair, the coat will need to be brushed a least twice a week. Many Spaniel owners take their pets to professional groomers to get the coat and ears trimmed.

Check your Spaniels ears inside and out regularly, because loving water the way he does, the ears inside can remain damp and become a breeding spot for infection.

Remember to also check your Field Spaniel’s teeth as dental disease can be the root cause of many diseases.

Diet:

Your Field Spaniel is an active breed and you want to be sure to feed him a high-quality commercially manufactured dog food which has been formulated for his activity level. Every now and again mix in some cooked brown rice, vegetables and chicken and also add in a bit of raw meat from time to time. Ensure cool, fresh water is always available.
