Hello Natalia,

many years ago I had a retired greyhound that I used as an obiediance dog. I won many trials with him and won an Australasian obiediance championship in Perth 1980. He went on to become an Australian Obeidiance Champion (AOC). Tracking, and utility trials.
Greyhounds are vey intelligent animals and one of the easiest dogs to train for that activity.
I had him for 14 years, and 5 times a week I fed him raw meat (Beef) and kibble with vegies.The other two days I fed him 1 litre of milk and 8 slices of bread.
For breakfast, he got two slices of toast with vegemite.

He was the most affectionate dog I've ever owned and an unbelieveable obeidiance dog in all levels.

So feed him plenty of meat with plenty of omega 3 with an occassional brisket bone.
