Wolf of wilderness food
Breed: cocker mix, 7 years old
Previous food: vet concept
Positive: when he first had it, my dog didn't refuse this food but ate it all up. Goes down very well in terms of taste. The switch went well until he started going for a poo more often but no worrying changes to his poo.
Negative: my dog went for a poo 3 - 4 times a day for the first 7 days.
This got better over time.
