Feeding guidelines

See table for recommended daily feeding amounts for both weight maintenance and weight loss. These amounts are guidelines only. When feeding for weight maintenance, to help keep your dog in an ideal body condition adjust the daily amounts according to your dog's activity level, physical condition and individual needs. If your dog is over his ideal weight, for a safe rate of weight loss follow the guidelines and adjust the amounts to target an average monthly loss of 2 to 4% of body weight. Clean, fresh water should be available at all times. To monitor your dog's health, consult a veterinary surgeon regularly.

Very happy with the quality and value after changing from a vet prescribed weight loss food for my Lab which became too expensive. My Lab seems to enjoy eating this but it is still early days to say how it helps with her weight loss but I am confident it will work long term.

55 Dog loved it

By on 25 February 2019

I normally have to mix dry food and wet food for my 2 year old lab. As soon as I put the food down he chomped away never had to give wet food with it. Well I have noticed as well he is calmer and has lost weight as well. The negative side is its not cheap. Other than that one thing I would recommend this to anyone.

Is this food suitable as a hypoallergenic?

  • VioVet Staff

'Hypoallergenic' as a term implies that the product causes 'fewer allergic reactions' than other diets. Whether this is the case will greatly depend on what your dog is allergic to. If they are not allergic to the ingredients within this food then yes, it will be hypoallergenic for your dog. However if your dog is allergic to one of the ingredients then it will be very allergenic.
If you would like specific dietary advice then please get in touch with what your dog is allergic to at [email protected] We can then recommend some appropriate diets that will be hypoallergenic for your dog.
