K9 Optimum Medium/Maxi Senior review

60/100Good
DryAdultSenior

A Good senior kibble that keeps its energy up and puts its age-related care in the extras. Chicken leads twice, 20% freshly prepared and 17% dried, with salmon at 4%. Glucosamine, methylsulphonylmethane and green lipped mussel sit at the foot of the list for the joints, and taurine and carnitine are dosed on the panel.

Our view

Likely to suit

  • Older medium and larger dogs, who are exactly who the label is written for
  • Stiffening joints: glucosamine, methylsulphonylmethane and New Zealand green lipped mussel are all in
  • An ageing heart, with taurine at 850 mg per kilo
  • Dogs that still want a meaty bowl, chicken at 20% fresh and 17% dried
  • A mixed-age pair sharing one bag, as the label runs from adult to senior

Worth watching

  • Energy at 362 kcal per 100g, no lower than the 357 typical of adult dry food, so portions matter for a dog slowing down
  • Salmon and salmon oil both on the list
  • Rice and maize high up, and no quantity on any joint entry
