When to contact a vet about your dog's diet

Safety first

Contact a veterinary surgeon if your dog is unwell, has a diagnosed condition, is under 12 months old, is pregnant or lactating, is on prescription food, or shows emergency symptoms. Dog Food Fix is for educational nutrition guidance for healthy adult dogs only. It does not replace veterinary care.

Situations where a vet should come first

In these situations, Dog Food Fix is not the right starting point. A veterinary consultation should happen before any dietary changes.

Puppies under 12 months — their nutritional needs are different and change rapidly
Pregnant or lactating dogs — require specialist dietary management
Dogs on prescription or therapeutic diets — never change without veterinary approval
Diagnosed kidney, liver, pancreatic, or cardiac disease
Diabetes or oncological conditions under treatment
Chronic vomiting or diarrhoea lasting more than 48 hours
Blood in stool, urine, or vomit
Unexplained weight loss exceeding 10% of body weight
Refusing food for more than 24 hours
Severely underweight (BCS 1–2) or obese (BCS 8–9)

When Dog Food Fix can help

Dog Food Fix is designed for healthy adult dogs whose owners want to:

  • Understand the quality of their current food based on the label
  • Check whether the daily portion is roughly appropriate
  • Compare their current food with alternatives in the database
  • Plan a safe, gradual transition to a new food
  • Learn about ingredients and nutritional principles

Frequently asked questions

Can Dog Food Fix diagnose food allergies?

No. Food allergies can only be diagnosed by a veterinarian, typically through a controlled elimination diet. Dog Food Fix may note common allergens on a label, but this is educational information, not a diagnosis.

My dog has soft stools — should I see a vet or use Dog Food Fix?

If soft stools persist for more than 48 hours, contain blood or mucus, or are accompanied by other symptoms (lethargy, vomiting, weight loss), see a vet first. If your dog is otherwise healthy and you suspect diet quality, a food report may help you review the current diet.

Will the report tell me what food to buy for my sick dog?

No. Dog Food Fix does not make recommendations for dogs with diagnosed conditions. If your dog has a health issue, your treating veterinarian is the right person to advise on diet.

What happens if the safety screen flags my dog?

If the intake form identifies a red flag, the system stops the flow before payment and recommends that you consult your local veterinarian. No charge is taken.
