Cons and what to keep in mind
- Not a joint supplement replacement. The dose is lower than in therapeutic supplements.
- Seafood. Not for dogs allergic to fish or shellfish.
- Calories. Treats count towards the daily intake.
- No weight-based amount in the description. Keep treats under 10% of daily calories.
Who benefits from joint support
Large and giant breeds, senior dogs, overweight dogs, sporting and active dogs, and dogs recovering from injuries. Signs of joint problems include stiffness after sleep, reluctance to jump or climb stairs and limping after walks. With these signs, see a vet: arthritis usually calls for a proper joint supplement course such as Candioli Confis Ultra. More on age-related changes in senior dog nutrition and care.
How to give treats properly
Treats are rewards, not meals. All treats in a day shouldn't exceed 10% of daily calories, or the dog will gain weight — and extra kilos load the joints even more. Break treats into small pieces: for training, frequency of reward matters more than size. More in dog training treats and overweight cats and dogs. Fresh water must always be available.
Functional treats vs chews
Semi-soft treats are great rewards but don't clean teeth or keep a dog busy for long. For occupation and dental care, chews work better — see how to choose dog chews.
Who it suits
Adult and senior dogs, large breeds, active and sporting dogs, and weight-prone dogs that need a low-fat reward with joint support. Puppies have their own treats — see puppy treats.
Verdict
Brit Functional Snack Mobility is a low-fat, grain-free squid treat with a set of joint-support ingredients. It's a nice addition to the diet and a good training reward, but with arthritis it should be paired with a proper vet-recommended joint supplement.
