Introduction
Many dog owners may wonder if feeding their dog cat food can help their underweight pet gain some much-needed weight. Cat food tends to be higher in fat and calories than dog food, so it may seem reasonable to try cat food to help a dog gain weight.
However, there are some important differences between cat and dog foods that make feeding cat food to dogs risky. Cats and dogs have different nutritional requirements, and cat food does not provide the right balance of nutrients for dogs. Eating cat food long-term can potentially lead to vitamin deficiencies, pancreatitis, and other health issues in dogs.
This article provides an overview of the key differences between dog and cat foods and examines the safety and health implications of feeding cat food to dogs. It outlines healthier approaches owners can take to help underweight dogs gain weight in a safe, gradual manner that supports their wellbeing. The goal is to inform owners about whether cat food is an advisable option for helping dogs gain weight.
Nutritional Differences Between Dog and Cat Food
There are important differences in the nutritional composition of dog and cat food. Cats are obligate carnivores, meaning they need a high amount of protein and fat from animal sources in their diet 1. Cat food is specially formulated to be higher in protein and fat compared to dog food.
On average, cat food contains about 40% protein and 16% to 20% fat, while dog food contains around 25% protein and 8% to 15% fat2. The increased protein and fat in cat food helps meet cats’ higher energy needs and metabolic demands.
Cats also require more amino acids like taurine, arginine, and methionine in their diet. Taurine deficiency can lead to blindness and heart problems in cats. As obligate carnivores, they lack the ability to synthesize these amino acids and must obtain them from animal-based proteins 3. Cat foods have added taurine and increased levels of amino acids essential for cats’ health.
The higher fat and protein content make cat food much more calorie dense than dog food. While this matches the dietary needs of cats, these levels can be unhealthy for dogs, especially if fed free-choice.
Can Dogs Safely Eat Cat Food?
There are some potential risks associated with feeding cat food to dogs on a regular basis. Cat food is very high in protein and fat compared to dog food. While these nutrients are essential, the high amounts in cat food can lead to health issues for dogs when eaten regularly.
One of the main risks is pancreatitis. The high fat content in cat food can cause inflammation of the pancreas in dogs. Pancreatitis can be a very painful condition and lead to vomiting, diarrhea, loss of appetite, and abdominal pain. In severe cases it can even be fatal [1].
Another potential issue is obesity and weight gain. Cat food has nearly double the calories per cup compared to dog food. The high fat and calorie content could quickly lead to obesity if a dog eats cat food daily. Obesity can contribute to arthritis, heart disease, and diabetes in dogs [2].
Kidney disease is also a concern, as the high protein content puts extra strain on the kidneys over time. Additionally, cat food lacks some vitamins and minerals dogs need for balanced nutrition long-term.
While the occasional bite of cat food won’t harm an adult dog, regular feeding of cat food can put dogs at risk for serious health problems. It’s best to stick to dog food formulated specifically for a canine’s nutritional needs.

Benefits of Cat Food for Weight Gain
One potential benefit of feeding cat food to dogs is that cat food tends to have a higher calorie density than many dog foods. Cat foods are formulated with higher fat and protein levels to meet the nutritional needs of cats, who have evolved as obligate carnivores and require higher levels of these nutrients. Dog foods, on the other hand, often contain more carbohydrates and fiber.
For example, a typical dry cat food may contain about 350-400 calories per cup, whereas many dry dog foods range between 250-350 calories per cup. The higher calorie density of cat food means that a dog will take in more calories eating the same volume of food.
This increased caloric intake from cat food can be beneficial for helping underweight dogs gain the weight they need. However, as discussed below, there are healthier ways to increase calorie intake for dogs that do not involve feeding cat food.

Healthier Ways to Help Dogs Gain Weight
There are a few healthy ways recommended by veterinarians to help underweight dogs gain weight in a safe manner:
– Feed a high-quality commercial dog food designed for weight gain. Veterinary nutritionists formulate these foods with optimal levels of protein, fat, and carbohydrates to promote healthy weight gain (1). Look for brands that use high-quality ingredients and have undergone feeding trials.
– Add healthy fat sources like omega-3 rich fish oils or coconut oil to your dog’s meals. Adding 2-4 tablespoons of oil provides extra calories from healthy fats (2).
– Mix in some canned food, meat broths, or meat baby food to make the food more enticing and energy dense. An extra spoonful or two of wet food helps increase calorie intake (3).
– Offer smaller, more frequent meals throughout the day. Feeding your dog 4-6 smaller meals rather than one or two large ones ensures they finish each serving.

Portion Control and Feeding Techniques
To help an underweight dog gain weight in a healthy manner, it’s important to focus on portion control and feeding techniques. This allows the dog to get the extra calories needed without overeating or eating too fast.
Feed your dog smaller, more frequent meals throughout the day. For example, break up the daily food into 4-5 smaller meals rather than 1-2 larger ones. This prevents your dog from gorging and gives the stomach time to empty between meals.
Make sure to precisely measure out the proper portion sizes for each meal. Don’t free feed, as letting your dog graze all day can lead to overconsumption. Stick to the recommended amounts per your vet or the dog food packaging.
Invest in a slow feed bowl or ball to slow your dog’s eating pace. Gulping food too quickly can lead to vomiting, bloating, and other digestive issues. Slowing the pace allows your dog to feel full on less food. You can also add warm water to dry kibble to soften it and require more chewing.
Schedule meal times and supervise your dog during feeding. This prevents sneaky snacking between meals. Crating your dog or separating from other pets during meal times can help focus their attention on eating.
With the right portion control and feeding techniques, you can safely help your underweight dog gain a healthy amount of weight over time. Consult your vet if you have any concerns.
Exercising an Underweight Dog
While a healthy diet is essential for weight gain, exercise also plays an important role for underweight dogs. Exercise helps build lean muscle mass which raises a dog’s metabolism and supports healthy weight gain. When exercising an underweight dog, focus on low-impact activities that gradually increase muscle strength without putting too much strain on their body.
Swimming is an excellent low-impact exercise for underweight dogs. The buoyancy of water supports their body weight and avoids stress on joints. Start with short 5-10 minute swimming sessions and gradually increase duration as the dog builds stamina. Always monitor the dog carefully and end the session if they show signs of fatigue (BetterPet).
Other good low-impact exercises include leash walking over flat terrain, playing fetch with soft toys, and doing basic obedience commands. As the dog gets stronger, walk times can be lengthened and hills can be introduced. Activities that build specific muscle groups like weight pulls, harnesses, and ramps can also help build strength. The key is starting slowly and monitoring for over-exertion.
Avoid strenuous activities like jogging or agility training which could stress the body. The goal is controlled, gradual strengthening to support healthy weight gain. Consulting a veterinarian can help develop the ideal exercise plan for an underweight dog’s needs and capabilities.
When to Seek Veterinary Care
If your dog’s weight loss seems extreme or has happened very rapidly, it’s important to schedule a veterinary visit. Sudden or severe weight changes can signal an underlying illness that requires treatment.
Some conditions that can lead to weight loss in dogs include:
– Dental disease
– Cancer
– Diabetes
– Thyroid disease
– Kidney disease
– Intestinal parasites
– Inflammatory bowel disease
Your veterinarian can perform a physical exam, take lab tests, and evaluate your dog’s overall health to pinpoint any condition causing weight issues. Getting an accurate diagnosis allows proper treatment to be initiated to manage the disease and support your dog’s weight gain efforts.
Even if an identifiable illness isn’t found, your vet can still provide tailored nutritional and exercise recommendations to help your underweight dog fill out to a healthy weight. Don’t hesitate to seek veterinary care if your dog seems abnormally thin.
Monitoring Weight Gain Progress
It’s important to monitor your dog’s weight gain progress to ensure they are gaining weight at a healthy rate. Here are some tips for monitoring your dog’s progress:
- Weigh your dog regularly – aim to weigh them at least once a week. Track their weight on a chart to ensure they are steadily gaining. Aim for your dog to gain 2-4% of their body weight per week.
- Assess your dog’s body condition – run your hands over their ribs and feel for any prominent bones. As they gain weight, they should start to fill out. You should be able to feel their ribs but they shouldn’t be highly visible.
- Monitor energy levels – make sure your dog still has good energy as they gain weight. Weight gain shouldn’t make them lethargic or low energy.
If your dog is gaining weight too rapidly, you may need to cut back on portions or calories. A steady, gradual increase is healthiest. Contact your vet if you have any concerns about your dog’s weight gain progress. With patience and monitoring, you can help your dog achieve a healthy weight.

Conclusion
In summary, while an underweight dog may seem to benefit from the higher fat content in cat food, feeding dog food specifically formulated for your pup’s life stage, size, and activity level is the healthier approach. Focus on choosing a high-quality dog food and feed appropriate portions for gradual weight gain. Exercise caution with free feeding, which can lead to overeating. Vet checkups can ensure your dog is gaining weight safely and help determine if an underlying medical issue needs to be addressed.
Avoid letting your dog graze on cat food, which can lead to nutritional imbalances over time. While the extra calories may seem attractive for adding pounds quickly, the health risks outweigh potential benefits. Instead, keep working closely with your veterinarian and stick to a tailored diet and exercise plan for your dog. With patience and consistency, you can help your underweight pup reach a healthy weight safely.
