Switching Pet Food: Signs Your Dog or Cat Isn’t Adjusting Well
Making the switch to new pet food can feel like a fresh start – maybe your fur baby needs a special diet, you've found a brand that’s more aligned with your values, or your vet recommended a nutritional change. Whatever the reason, transitioning to new food can sometimes come with a few hiccups. At Petdirect, we get that your pet’s health and happiness is top priority. So if you’ve recently changed your cat or dog’s diet, here's how to tell if they’re not adjusting well, and how to help.
Common Signs Your Pet Isn’t Agreeing With Their New Food
Just like us, pets can have sensitive tummies or be picky eaters. If your cat or dog isn’t tolerating new food well, they might show one or more of these signs:
- Tummy troubles: Watch for diarrhoea, vomiting, or constipation. These can be signs their digestive system is struggling.
- Eating less or refusing food: It could be taste, texture, or even the smell that’s putting them off.
- Excessive gas: More farting than usual – it’s not just smelly, it could signal discomfort or poor digestion.
- Itchy skin or coat changes: Food sensitivities can impact skin and fur health.
- Lethargy or behavioural changes: If your usually energetic pup is suddenly sluggish or your sassy cat is hiding away, it might be linked to their diet.
If any of these symptoms last more than a few days, it's a good idea to chat with your vet, especially if there’s vomiting or diarrhoea. While minor symptoms can sometimes be part of transition, persistent or serious ones need attention.
Why Transitioning Food Gradually Is So Important
The number one trick to a smooth diet change? Take it slow. Whether you’re introducing dry food, wet food, or a raw or freeze-dried option, switching too quickly can lead to upset stomachs and refusals.
A simple transition plan over 7–10 days looks like this:
- Days 1–2: 75% old food, 25% new food
- Days 3–4: 50/50 mix
- Days 5–6: 25% old, 75% new
- Day 7+: 100% new food
Some dogs and cats will need even more time. Start with small amounts and monitor how they respond with each stage.
Choosing The Right Food For Your Pet
Not all pets thrive on the same food. Considering your pet’s life stage, breed, health conditions, and preferences is essential. At Petdirect, we stock a wide range of premium options including Royal Canin, Hill’s Science Diet, ZIWI, and Feline Natural, all designed to meet the unique nutritional needs of New Zealand pets.
Don't forget to consider supplements too – products from our supplement collection can help support digestion and immunity through the food transition period.
How To Encourage Fussy Eaters
Got a choosy cat or discerning dog? Try these tricks to tempt their taste buds:
- Warm up wet food to release aroma
- Add a spoonful of toppers or mixers for extra flavour and variety
- Serve food in a clean bowl – lingering smells can put pets off
- Stick to a regular feeding schedule
- Use smart water fountains to encourage proper hydration with their meals
When your pet associates their new food with positive experiences, they’re more likely to accept it.
Helping Support Their Tummy During The Switch
If your pet seems a little off but not unwell, they may just need extra digestive support. Look into digestive health supplements that contain probiotics or fibre to keep things running smoothly. Some calming aids may also help if your pet is dealing with the stress of a food change.
Still unsure which food is right? Our Petdirect team knows pets and love helping you find the paw-fect match. From locally made diets to science-backed formulas, we’re here to support you every meal of the way. Because at Petdirect, We Get Pet.
When To Speak To A Vet
If symptoms persist, your pet refuses to eat altogether, or you notice weight loss, it's best to consult your vet. In some instances, a prescription vet diet may be recommended for dogs, or a vet-approved formula for cats. These are formulated to support pets with allergies, gastrointestinal issues, kidney disease and more.
Helping Your Pet Thrive On Their New Food
Transitioning pet food is a journey, not a race. By easing your dog or cat into their new diet slowly and keeping an eye out for tell-tale signs of tummy upset or disinterest, you’ll help them adjust smoothly and happily. And if things don’t go to plan? You’re not alone – our expert Petdirect team is ready with guidance, trusted food brands, wellness supplements, and helpful tools to support you at every step.
