I have 3 dogs - a Bernese Mountain Dog (2yo) and 2 Basset Hounds (a 5yo and a ~8+?yo). Right now I have them all on the same food, Purina Pro Plan Savor Lamb and Rice, which they seem to be doing well with. Shiny coats, good weight, good energy etc.
Should I switch the older guy to a senior food? I see the there’s a Pro Plan “Bright Mind” line for dogs 7+. He’s doing well on his current food and I like the convenience of them being on the same kibble but I wonder if he’s missing out on something? He also gets a Cosequin supplement, if that makes a difference.
