When planning to travel with our furry friends by air, many pet parents overlook a crucial question: not all pets are suitable for air travel. Here’s a comprehensive guide to help you understand which pets should avoid flying to ensure their safety.
1. Health Risks for Overweight Pets

When our pets exceed their ideal body weight by 15%, they are considered overweight. While their chubby appearance might seem adorable, it can pose life-threatening risks during flights. The confined space of transport carriers combined with air pressure changes can cause overweight pets to experience breathing difficulties and cardiovascular problems, potentially leading to fatal consequences.
2. Special Considerations for Brachycephalic Pets

Brachycephalic (flat-faced) pets such as Pugs, Bulldogs, Garfield cats, and Persian cats are beloved for their unique facial features, but these same characteristics make air travel particularly dangerous for them. Their shortened respiratory tract makes them prone to breathing difficulties during physical stress, and the environmental changes during flight can exacerbate these risks. It’s particularly important to note that shipping these types of pets during summer months should be strictly avoided.
3. Pets in Special Conditions
Pregnant pets require extra attention. The turbulence, pressure changes, and environmental transitions during flights can cause severe stress responses, potentially leading to miscarriage. For the safety of both mother and unborn offspring, alternative travel methods are strongly recommended.

Similarly, puppies and kittens under three months of age need special consideration. At this young age, they have weak immune systems and often haven’t completed their vaccination schedules. Professional pet shipping companies typically recommend waiting until pets are at least six months old before considering air travel, as this ensures better safety margins.
4. Restrictions for Sick Pets and Aggressive Breeds
For pets currently suffering from illness, the unique environment during flights can worsen their condition. Due to the nature of aircraft cargo holds, it’s impossible to monitor and respond to emergencies promptly, significantly increasing the risk factor.

As for aggressive breeds, such as Tibetan Mastiffs and certain Bulldog varieties, airlines typically deny boarding for safety reasons. If air transport is absolutely necessary, specialized high-quality aviation crates are required to prevent escape attempts.
Helpful Tips
Before planning air travel with your pet, we recommend:
- Research specific airline regulations well in advance
- Consult with a veterinarian
- Purchase an appropriate airline-approved carrier
- Prepare necessary health documentation
Remember, choosing the right mode of transportation is a responsibility we owe to our pets. If your pet falls into any of the above categories, consider alternative transportation methods to ensure a safer journey.
Final Thoughts
The safety of our beloved pets should always be the top priority when planning travel arrangements. While air travel might seem convenient, it’s crucial to consider whether it’s the best option for your particular pet’s health and well-being. Sometimes, choosing a different mode of transportation might take longer, but it could be the safest choice for your furry family member.
