Exercise:

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.

Diet:

They have additives in them such as fish oils which decrease inflammation. Always look for a food that is appropriate for your dog’s age and energy levels.

Add in your own home-made food to his dry kibble such as cooked chicken, brown rice and pasta as well as vegetables and also try to include some raw meat into his kibble from time to time. Fresh, cool water should be available to him night and day.

Grooming:

With his short coat, the dog is looked upon as low maintenance. Brush him a couple of times a week to make sure the coat remains shiny. Check his eyes, ears and teeth for infections.

Exercise:

This dog is lean, energetic and agile. With his long strides, he likes to run over terrain sniffing and following scents. He is more suited to life in the countryside than to the city. Make sure you have a reasonable sized garden for him and meet his exercise needs by taking him on walks and playing ball and fetch games with him.
