Can Dogs Take Ozempic? The Truth About GLP-1 Weight Loss for Pets in 2025
With 60% of American dogs classified as overweight or obese in 2025, and human weight loss drugs like Ozempic making headlines, many pet owners are asking: Can my dog take Ozempic?
As a veterinarian with 15 years of experience, I'm seeing this question more than ever. Here's everything you need to know about GLP-1 drugs for dogs, FDA-approved alternatives, and safe weight loss strategies for your pet.
What is Ozempic and How Does It Work?
Ozempic (semaglutide) is a GLP-1 receptor agonist approved for humans with type 2 diabetes and obesity. It works by:
- 🧬 Mimicking GLP-1 hormone that regulates appetite
- 🍽️ Reducing hunger and food intake
- 🔄 Slowing gastric emptying (you feel full longer)
- 📉 Lowering blood sugar levels
Sounds perfect for overweight dogs, right? Not so fast.
❌ Can Dogs Take Ozempic? The Short Answer
No, dogs should NOT take Ozempic (or other human GLP-1 drugs like Wegovy, Mounjaro, or Saxenda).
Here's why:
1. Not FDA-Approved for Pets
Ozempic is only approved for human use. Using it in dogs is considered "off-label" and carries significant risks.
2. Different Metabolism
Dogs metabolize medications differently than humans. What's safe for you could be toxic for your pet.
3. Serious Side Effects
GLP-1 drugs can cause in dogs:
- Severe vomiting and diarrhea
- Pancreatitis (life-threatening)
- Dehydration
- Thyroid tumors (shown in rodent studies)
4. Cost & Availability
Ozempic costs $900-$1,400/month and there's a shortage. Your vet has better, cheaper options.

🏆 The Best Way to Help Your Overweight Dog (No Drugs Needed)
Before considering medication, try these veterinarian-approved strategies:
1. Calculate Proper Calories
Use our Pet Calorie Calculator to find your dog's ideal daily intake.
Example:
- 50 lb overweight dog
- Target weight: 40 lbs
- Daily calories: ~800 kcal (for weight loss)
2. Measure Food Portions
- ❌ Don't free-feed or eyeball portions
- ✅ Do use a measuring cup
- 📉 Reduce current food by 25% gradually
3. Increase Exercise
- Start with 20-30 minutes daily
- Swimming (low-impact for joints)
- Play fetch, tug-of-war
- Dog parks for socialization
4. Eliminate Table Scraps
- One slice of pizza = 20% of a small dog's daily calories
- Switch to low-calorie treats (carrots, green beans, air-popped popcorn)
5. Monthly Weigh-Ins
Track progress. Healthy weight loss = 1-2% body weight per week.
