We've had dogs for twenty years and have always fed them kibble - each dog (mostly mixed breeds/rescues) has thrived and lived a long and happy life. We do however mix kibble with fresh vegetables (about 2:1 in ratio) with every meal, and we add frozen tripe and tinned sardines in oil once a week (on different days). For a treat we mix some wet food but that's a few times a year only.
We are keen to stick with kibble and our vet seems very happy with that. However I wanted to know if there are any additional foods that anyone else feeding kibble successfully adds to their dogs' diets. Eggs, yoghurt, fish, etc. I've read about multiple things you can add but wanted to hear first-hand experiences. Thank you.
