It can be tricky to know if your dog is getting too much protein in their diet. While protein is an essential nutrient for dogs, excessive amounts can cause health problems. Here are some signs that may indicate your dog is getting more protein than they need.
Weight Gain
One of the most obvious signs of too much protein is if your dog starts to put on excess weight. Protein contains calories, so overfeeding protein can lead to obesity in dogs. Pay attention if your dog’s ribs become harder to feel or their waistline starts to thicken.
Gastrointestinal Upset
Too much protein can irritate your dog’s digestive system and cause loose stool or diarrhea. Their stools may become very smelly and abnormal looking. Some dogs may also vomit if they are getting more protein than they can handle.
Dehydration
Protein digestion requires more fluids. So if your dog is taking in too much protein, it can lead to dehydration. Signs of dehydration include lethargy, loss of appetite, dry gums, and dark yellow urine.
Kidney Problems
Over time, excessive protein levels put strain on your dog’s kidneys to eliminate the protein byproducts. Kidney disease often has no obvious symptoms until it becomes advanced. Your vet can test your dog’s kidney values with a blood test.
How Much Protein Do Dogs Need?
The amount of protein your dog needs depends on their life stage:
| Life Stage | Protein Requirement |
|---|---|
| Puppy | 22% to 32% of total calories |
| Adult (maintenance) | 18% of total calories |
| Adult (active/working) | Up to 32% of total calories |
| Senior | 18% of total calories |
Puppies and active, working dogs need more protein to support growth and their higher energy needs. Adult dogs at maintenance require less.
Signs Your Dog’s Food May Have Excessive Protein
When looking at your dog’s food, here are some things that may indicate it contains too much protein:
- Crude protein is over 32% for an adult dog
- First several ingredients are meat or meat meals
- No carbohydrate ingredients like grains, potatoes, or peas
- Label markets the food as “high protein” or “grain-free”
What to Do if Your Dog is Getting Too Much Protein
If you suspect your dog is getting too much protein, here are some steps to take:
- Consult with your vet to rule out other medical issues causing symptoms
- Review your dog’s diet and look for ways to reduce protein levels
- Gradually transition your dog to a food with lower, more appropriate protein content
- Ensure your dog always has access to fresh water to stay hydrated
- Monitor your dog for improvement in any symptoms
- Have your vet run routine kidney function tests
Tips for Choosing a Lower Protein Dog Food
- Look for a protein content around 18-22% for most adults
- Aim for foods with a carbohydrate source in the first 5 ingredients
- Choose diets made for mature dogs if needed
- Select a food formulated for your dog’s activity level
- Ask your vet for brand and formula recommendations
Conclusion
While protein should make up a significant portion of your dog’s diet, excessive amounts can be harmful. Pay attention for signs like weight gain, tummy troubles, dehydration, or kidney issues that may indicate protein overload. Follow your vet’s feeding guidelines, and gradually transition to a more balanced food if needed. With the right diet, your dog can get the nutrients they need without going overboard on protein.
