"Animals are such agreeable friends - they ask no questions; they pass no criticisms," this quote was uttered by George Eliot. And that's absolutely true! Many pet owners will agree on that. There's a film shown this year entitled "The Secret Life of Pets." In the movie, a Jack Russell Terrier named Max is patiently waiting for her master and best friend, Katie. He had a conversation with Gidget, a white Pomeranian.

The talk between Max and Gidget represents how loyal pets are to their owner. They're job is to wait and wait until their master comes back. But the scene should not always be like that because you can tag along your furry buddies in your travel too. Here are some of the guidelines that you should bear in mind before granting them a vacation break:

1. Feed the dog at least an hour before it sits in the car and just give small portion, same with the drinking water. Dogs also feel sick in their stomach while the car starts moving.

2. Give him a good walk. This way he will feel calm and tired. He will fell asleep easily once he hopped in the car.

3. Keep their heads inside the car and don't allow them to stick it out on the window. Some particles or debris might come inside their nose and goes down their lungs. They can also jump out of it, so better lock up or leave it half open.

4. Take a break frequently, carry your dog out of the car and exercise by walking him around even just a few minutes.

5. If you want to transport your pet, driving by land is the best option. But if travelling by plane is the only way, you must check all the airline guidelines and book ahead of time. The Humane Society of the United States recommends that you evaluate all the dangers when deciding to bring them on plane ride. It can be dangerous for animals with "pushed in" faces because their nasal passages are short that leaves them vulnerable to oxygen deficiency and heat stroke.

Pushed-in face is a term associated with brachycephalic breed; animals like Himalayans and Persians cats, pug, bulldog, Pekingese and Shi Tzu are some of the examples. These pets have short heads, short-muzzled breeds. Because of this, animals like this have what is called brachycephalic respiratory syndrome to varying degrees.
