For some dog breeds, eating is perhaps a question of quantity rather than quality (here’s looking at you labradors 
). And some dogs may require specialist diets. But for most dogs, eating is a functional pleasure.
As experienced, international housesitters then we come across all manner of different approaches to dog food. Kibble; supermarket wet food; frozen mail-order; homemade; raw; BARF; human food; all sorts. While a few dog food brands seem internationally available then many seem national or local. The diversity of dog eating experiences across our housesits has been extensive.
Our current UK housesit uses Bella & Duke frozen mail-order dog food. The dogs clearly adore it. Obvious excitement. Excited pirouettes. Permission eating. A real treat to observe. Happy happy dogs 
Makes us wonder from housesitter community what food styles and brands make dogs jump for joy at each mealtime?
