Hunting dogs eat just about anything (including your birds, if you aren’t careful), but adult hunting dogs should really just eat quality dog food and, sure, vet-approved treats. Buy kibble from a reputable dog food brand and, if you have the budget, choose a formula created for sporting breeds, which contain extra protein and fat for active dogs (like Purina Pro Plan Sport 30/20 or Eukanuba Sporting Dog). Beware trendy dog food products advertised in your Instagram feed, which often don’t have many of the essential nutrients dogs require.
