When a dog passes away, its heart will stop beating. To check for a pulse, place two fingers either on your dog’s chest where its heart is located (near the elbow joint), or high up on your dog’s inner thigh where a major artery is located.  If there is no pulse, then your dog has passed away. If your vet euthanizes your dog, they will check for a pulse after administering an overdose of a drug that gradually slows the heart until it stops. Breathing may continue even after a dog’s heart has stopped. To check for breathing, hold a small mirror near your dog’s nostrils. If your dog is still breathing, a small amount of condensation will form on the mirror. You can also hold a tissue in front of the nose or mouth and see if it moves.  After at least several seconds, if you do not see condensation on the mirror or the piece of tissue doesn’t move, that means your dog is not breathing. If you know its heart has also stopped beating, you will know at this point that your dog has passed away. As your dog is taking its last breath, it may stretch its head back and stretch out its legs. When your dog has passed away, its eyes will be open. The eyes will have a vacant look, as if your dog is staring into space. The pupils will be dilated (large and black) and your dog will not blink when you tap the corner of its eye. Your dog’s body has electrical activity that helps coordinate muscle movement. Even after your dog’s breathing and heartbeat have stopped, its leg muscles may twitch for a little while. This does not mean your dog is alive. Instead, it means there is still some electrical activity in the muscles. Eventually, all the electrical activity will run out and your dog’s muscles will stop twitching.

Article: Liquids and gels in your carry-on bag are limited to 100ml (3.4 oz) and need to be sealed in a clear plastic bag before flying. Pack your toiletries into this plastic bag before going to the airport to avoid delays at the security check. All containers of liquids, aerosols, or gels must go in this bag.  For flights to the U.S. it helps to know the 3-1-1 rule. This rule means that all liquid containers of 3.4 ounces or less (‘3’) must be stored in a single, clear, sealable bag (‘1’) which is limited to 1 per person (‘1’). Medications are exempt from this restriction.  Store this plastic bag in an outer pocket, so that it may be easily removed from your carry-on bag at the security checkpoint. If you have any essential medication that must travel with you, make sure you bring it along. Most medication is subject to a screening at the security checkpoint, so keeping it in its original packaging will ensure you are not delayed in your travels. While most airlines will provide you with a small toothbrush and toothpaste set for your long-haul flight, it is always best to pack your own. Being able to brush your teeth will greatly enhance your comfort on the flight. If you like to talk to your traveling companions when you fly, having fresh breath will help your confidence and make the conversation flow more smoothly. Visiting the restroom on a plane can feel pretty gross sometimes. Packing a small container of hand sanitizer to use after trips to the restroom will make you feel much cleaner. The air in airplanes tends to be drier than average. If your skin tends to dry out, bring along some moisturizer and use it regularly. To stop your lips from drying out and cracking, use a gentle lip balm. Unfortunately, there’s no escaping body odor on a long flight. With no access to a shower on the plane, you’re likely to feel quite smelly by the end of your trip. Deodorant is the next best thing, so make sure to bring some along. Having easy access to your feminine hygiene products can take a lot of the stress out of long-haul flights. It sucks being caught unaware, so pack these just in case.
