Pet weight management - signs to notice and a safe plan with your vet

Extra weight can affect a pet’s comfort and health, but appearance alone cannot tell you whether a dog or cat needs to lose weight. Breed, frame, age, muscle and health all matter. A veterinary team can assess body condition and make a safe plan for that individual animal.
What you can notice at home
Look for a gradual change in body shape, a less visible waist, ribs that are harder to feel, or a pet tiring sooner during familiar activity. These are prompts to arrange a routine check—not a diagnosis. Take a side and overhead photo every few weeks in similar lighting, and note any change in mobility, appetite or energy. Avoid comparing your pet with photos of other animals; healthy shape varies.
Build a plan with the veterinary team
- Ask for a weight and body-condition review. Request a target, a suitable diet and a follow-up date. The AAHA nutrition and weight guidelines recommend an individual assessment rather than a one-size-fits-all plan.
- Write down everything your pet eats. Include meals, treats, chews, table scraps, food used for medication and food given by every household member.
- Agree on portions and changes. Do not sharply cut food or switch to a weight-loss diet without advice, especially for a growing, ill, senior or underweight animal. Cats in particular can be harmed by not eating enough.
- Use activity your pet can manage. Ask what is suitable if your pet has pain, breathing problems, heart disease or limited mobility. Increase activity gradually, not as punishment.
- Track progress and adjust with the team. Regular weigh-ins show whether the plan is working and whether portions or goals need changing.
Food can be part of bonding, so replace some treats with play, brushing or calm attention where appropriate. If more than one person feeds the pet, keep a shared daily record. Never use a human weight-loss product or medicine unless a veterinarian has specifically prescribed it for your pet.
Where Collar fits
For health questions, Collar is not a diagnostic or treatment tool. Its role is practical: help you keep your pet profile and service bookings organised, and make it easier to contact a participating care provider. Ask a veterinary professional to interpret symptoms, records and treatment.
The experience depends on the services each provider has enabled. Explore the Collar app.
