How Can I Help My Pet’s Joints and Weight at Home?
Share
As a pet owner, you might notice your dog slowing down on walks or your cat hesitating to leap up to their favorite perch. It’s natural to worry about keeping your furry friend active and comfortable, especially as they age or gain a few extra pounds. Joint comfort and healthy weight go hand in hand—understanding how to support both can make a real difference for your pet.
Key Takeaways
- Carrying extra weight can put more pressure on your pet’s joints and may increase inflammation [1].
- Even small amounts of weight loss can help dogs with joint problems move more easily [2].
- Omega-3 fatty acids (EPA) have the strongest evidence among supplements for supporting joint mobility in dogs and cats [3][4].
- Glucosamine and chondroitin supplements do not have strong evidence for joint pain relief in pets [5].

Why Does Extra Weight Affect My Pet’s Joints?
When pets carry extra body fat, it’s not just about appearance. Fat tissue can release substances that may drive inflammation and discomfort in the joints. This means overweight dogs and cats are at higher risk for joint problems like arthritis [1].
Extra weight puts more strain on your pet’s joints every day, which can speed up the wear and tear that leads to joint stiffness or pain. That’s why keeping your pet at a healthy weight is one of the most important things you can do for their joints [1].
Will Weight Loss Really Help My Dog Move Better?
Yes—even a small amount of weight loss can help your dog get up, walk, and play more easily. Research shows that managing your dog’s weight is the main way to slow down the development of arthritis. Even modest weight loss in overweight dogs with arthritis is well established to improve their ability to move [2].
Weight management is just one tool; it doesn’t replace other care your vet may recommend, but it’s a powerful way to help your pet feel better at home [2].
What About Omega-3s (EPA) for Joint Support?
You might have heard about omega-3 fatty acids, especially EPA, for joint comfort. Diets rich in EPA or omega-3 supplements have been shown to help dogs with arthritis move more easily. A 2022 review found that omega-3-enriched diets and supplements can provide real benefits for dogs and cats with joint problems [3].
Another study found that dogs eating food with added fish-oil omega-3s had higher blood levels of these healthy fats and showed improvements in getting up, playing, and walking [4].
Omega-3s have the strongest nutritional evidence among joint supplements, but they should be part of a complete care plan—not a cure-all [3][4].
Do Glucosamine and Chondroitin Work for Pets?
Many joint supplements include glucosamine and chondroitin, but what does the science say? A 2022 review and meta-analysis found that these supplements did not provide meaningful pain relief for dogs or cats with arthritis. Experts concluded they should no longer be recommended for managing joint pain [5].
This is a big contrast to the stronger support for omega-3 fatty acids. If you’re considering joint supplements, it’s worth discussing the latest evidence with your veterinarian [5].
Can Feeding the Right Amount Help My Dog’s Joints?
Feeding your dog just the right amount throughout their life can have long-term benefits for their joints. In a lifelong study of Labrador Retrievers, dogs fed 25% less food than their littermates developed hip arthritis much later—at a median age of 12 years compared to 6 years for dogs fed more [6].
This suggests that avoiding overfeeding and keeping your dog lean, especially during growth and adulthood, can help support healthier joints as they age [6].
Do Cats Get Arthritis Too?
Yes—around 60% of all cats, and over 90% of cats older than 12, can be identified as having joint disease. Arthritis is often missed in cats because they hide pain. Instead of limping, you might notice your cat jumps less, grooms less, or seems less active [7].
If you see these subtle changes, it’s a good idea to have your cat checked by a veterinarian [7].
Is Extra Weight Linked to Other Health Problems?
More than half of dogs and cats in the United States are overweight, and carrying extra pounds is linked to health problems like diabetes, certain cancers, and skin issues. Extra body fat also increases inflammation, which can make joint problems worse [8].
Keeping your pet at a healthy weight is about more than just movement—it’s about supporting their overall health and happiness [8].
How Many Treats Is Too Many?
Who doesn’t love giving treats? But treats should make up no more than about 10% of your pet’s daily calories. Too many treats can unbalance your pet’s diet and lead to weight gain. Most of your pet’s calories should come from a complete and balanced food [9].
Instead of counting treats, pay attention to your pet’s body shape and actual weight. This is a better guide than just following feeding labels [9].
Why Shouldn’t I Put My Overweight Cat on a Crash Diet?
If your cat is overweight, it’s tempting to cut back food drastically. But crash dieting or food deprivation can be very dangerous for cats, especially those already overweight. Sudden lack of food can trigger a serious liver disease called hepatic lipidosis. Overweight cats must lose weight gradually and never be starved [10].
Always work with your veterinarian to create a safe, slow weight loss plan for your cat [10].
Comparison Table: Joint Support Strategies—What the Evidence Says
| Strategy | Evidence for Joint Health? | Key Points |
|---|---|---|
| Weight loss in overweight dogs | Supported [2] | Even modest loss improves mobility; part of overall care |
| Omega-3 (EPA) supplementation | Supported [3][4] | Improves gait and mobility in arthritic dogs; strongest supplement evidence |
| Glucosamine/chondroitin supplements | Not supported [5] | No meaningful pain relief in studies |
| Lifelong healthy feeding (dogs) | Supported [6] | Delays onset of hip osteoarthritis |
| Crash dieting in cats | Not safe [10] | Can cause life-threatening liver disease |
Comparison Table: Signs of Joint Issues in Dogs vs. Cats
| Signs in Dogs | Signs in Cats |
|---|---|
| Limping or stiffness | Less willing to jump |
| Trouble getting up or lying down | Grooming less |
| Reluctance to play or walk | Less active overall |
| Slower on walks | Hiding or changes in behavior |
Quick fact: Over 90% of cats older than 12 can be identified as having degenerative joint disease [7].
What Makes PLATINUM’s Nutrition Different?
PLATINUM’s Fleischsaftgarung dry dog food is made with 70% fresh meat for adult dogs (73% for puppies) and contains no meat meals [11]. This high fresh-meat content is designed to provide quality protein, which helps maintain muscle as your pet ages [11].
PLATINUM’s dry dog food achieves a protein digestibility of 93%, which the brand describes as significantly higher than conventional extruded food. This can mean smaller, firmer stools that are easier to pick up [12].
PLATINUM’s recipes also include functional ingredients like salmon oil and flaxseed oil (sources of omega-3s), green-lipped mussel extract, and dried botanicals such as carrots and broccoli [13]. While these ingredients add nutritional value, no food or ingredient can treat or prevent specific diseases on its own [13].
If you’re looking for a food that supports your pet’s nutritional needs, exploring options with high-quality protein and functional ingredients may be a good place to start.
