 Today, thanks to social isolation and YouTube, I watched a video of Usain Bolt, the fastest man in the world, performing a warm-up routine. A trainer took each of his legs and put the hip and knee joints into flexion for about 1 second. Then Usain Bolt did some dynamic stretching, including normal running and running with high knees for short distances, and some sudden accelerations from a stopped position. A little walking around, and he was ready to go! In the comments section were many submissions like “I thought we weren’t supposed to stretch!” and “But he’s only stretching for a few seconds!” and so on.

 Did you know that your dog has something in common with vampire bats, pit vipers and black fire beetles? What could that possibly be?
It all started when some scientists from Sweden and Hungary went into a bar…. Well, that might not be exactly true. I’m not sure where they were when they got together and asked the question, “Why is a dog’s nose moist and cold, when most other mammals’ noses are warm and dry?” No doubt this is a question that has also kept you awake many a night… At first they considered that the canine cold wet nose might help with cooling in hot weather. But they discarded that idea because the surface area of the nose is just too small to make much of a difference.  Have you ever parked outside a restaurant or concert, had an exciting few hours, and then walked outside to realize you have no idea where you left your car? Why can we easily recall our childhood street address but forget something we knew just a short time earlier?
Just like us, dogs have short-term and long-term memory. Short-term memory helps us remember where we parked, or where to go next on an agility course. It helps your dog remember where he put the bully stick he was enjoying before he had to leap up and bark at the door when the doorbell rang. When we train our dogs, we want what they learn to persist much longer than a few hours. To accomplish this, those lessons need to be placed in long-term memory. Numerous studies have shown that reward-based training is the most effective way for dogs to learn. Dogs trained with positive reinforcement and without aversives are less stressed, which permits optimal learning. (Have you ever tried to memorize some facts with your boss or teacher staring at you as opposed to in the comfortable solace of your bedroom?) However, training methods aside, a recent study examined what kinds of post-training activities will help your dog send those newly learned lessons into long term storage.

Well that’s one wish that you can make come true! You can easily increase your dog’s life span by up to 2 years and it won’t cost you a thing. In fact, it will save you money! Too good to be true?
In 2019, a group of scientists published a study that looked at the lifespans of over 50,000 dogs of 12 different breeds living in North America (1). That’s a LOT of dogs! They asked a very simple question. What is the expected lifespan of dogs that are overweight when they visit a veterinary hospital in middle age (between 6 ½ and 8 ½ years) as compared to dogs that are of normal weight? |
