My personal choice is to feed my dogs as nature intended ( BARF in other words, bones and raw food). Their diet consists in the mornings of mushed vegetables, berries and fruits, mixed with meet, garlic and oil. In the evenings they mostly eat meaty bones and once a week fish or guts (all ingredients raw). Thrue work I have noticed that your dogs diet plays a major role in its wellbeing and immune system. Two years ago my eldest dog got a massive uterus and brest inflammation a week after whelping. She was operated five times in a two week period and before the last operation I was warned that she might not make it. Pequiña not only survived but recovered in no time, even the vet was astonished! I believe her diet was one of the main reason. Her daughter has been on raw food ever since her mothers woom and Mesteña is a healthy strong dog. If you are interested in feeding your dog with raw food and have some questions, I´m happy to help.
