Dogs’ feet give Japan scientists paws for thought

TOKYO (Reuters) -

Ever wonder how dogs can walk barefoot in the snow? Now a Japanese scientist may have the answer — an internal central heating system.

The secret lies in how dogs circulate their blood to prevent cold surfaces from chilling the rest of their bodies, according to Hiroyoshi Ninomiya, a professor at Yamazaki Gakuen University, just west of Tokyo.

The system uses warm, oxygenated blood to heat the cold blood that has been in contact with a cold surface before returning it to the dog’s heart and central circulation.

“Dogs exchange heat at the end of their legs. Arterial blood flows to the end of their legs and then heats up venous blood before returning it to the heart,” Ninomiya said of his findings, published in the journal Veterinary Dermatology.

“In other words, they have a heat exchange system in their feet.”

Ninomiya studied a preserved dog’s leg under an electron microscope and found that because of the proximity of arteries and veins in the foot pad, the heat in the blood carried from the heart to the arteries is easily conducted to the cooler blood in the veins.

This heat transference maintains a constant temperature in the foot pad, even when exposed to extremely cold conditions.

Dogs are not alone in having this sort of heat exchange system, which is shared by other animals such as dolphins, Ninomiya said.

But not all dogs thrive in the cold, due to refining by breeders seeking specific traits, he added.

“Dogs evolved from wolves, and so they still have some of that ancestry remaining,” he said.

“But that doesn’t mean that one should always go and drag around in the snow all the time. There are many varieties of dogs nowadays that are not able to stand the cold.”

Daily did you know that?

Loudest purr by a domestic cat

Guinness World Records is pleased to announce that Smokey, a 12 year-old female British short-hair cat, has been recognized as having achieved the Loudest purr by a domestic cat at 67.7 dB (LA peak).

Loudest purr by a domestic cat

Smokey is owned by Ruth Adams (UK) and lives at Spring Hill farm, Pitsford, Northampton, UK. Ruth said: “Smokey and I are very excited at being awarded the Guinness World Records™ title for the Loudest purring domestic cat. We originally started a purring competition in our home town of Northampton to promote the cats charity ‘Cats Protection’. We wish to thank all those who have supported Smokey with her record attempt and especially wish to thank Northampton College for organizing the trials and supplying the expertise I needed to comply with the technical aspects of a Guinness World Records Claim. We are very happy and purring loudly at the announcement that we hold a Guinness World Records title.”

Craig Glenday, Editor-in-Chief of Guinness World Records, said: “Guinness World Records is a veritable cat-alogue of fantastic felines, and Smokey is a welcome addition to the family. It’s incredible to think that a cat’s purr can be as loud as a vacuum cleaner!”

Further Information: The loudest animal sound is the low-frequency pulses made by blue whales (Balaenoptera musculus) and fin whales (B. physalus) when communicating with each other. These whales reach an amazing 188 dB on the decibel scale, creating the loudest sounds emitted by any living source. Total silence is 0 dB, a lawnmower – 90 dB, car horn – 110 dB, – a rock concert — 120 dB. Blue whales and fin whales are louder than all of these!

The Fastest Car Window Opened by a Dog:
The fastest time a dog has unwound a non-electric car window is 11.34 seconds and was achieved by Striker, a Border Collie owned and trained by Francis V. Gadassi (Hungary). The record was set on September 1, 2004 in Quebéc City, Canada

Striker the window rolling dog!!! Bet he’s a handy passenger for cars with manual windows on a hot day!

From the Montreal Dog Blog. Poop Sandwiches! Yuck!

Ask A Trainer: Poop Sandwiches
By Nat
Ask A Trainer — 10 November 2010

Q: My 4 month old Yorkie eats his poop. We have tried putting the powder on his food a vet recommended and also changed to Pediatric food but he continues to eat it. What can we do to make him stop eating his poop?

(See what the Dog Blog Vet had to say about this issue!)

 

Now, read the trainer take:

Hi there! Thanks for writing in with such a great question. Although it’s not talked about very much, you are not alone in owning a dog who likes to eat his own poop! There are quite a few dogs who engage in coprophagia actually. I know of more than few dogs who share this dirty little secret!

The thing about dogs eating either their own poop, another dogs’ poop, cat poop, or any animal poop is that it is completely revolting to us people, understandably! We just can’t imagine, or stomach watching our adorable love-bugs munching down on a fresh pile of his own poop. Eww! And god forbid, let him wriggle on over to cover us with slobbery poopy kisses!

But in the doggy world, this is a completely normal canine behavior. I know, you just gagged, but it’s true. And it doesn’t bother the dog one bit. The ones who do it really love it, as disgusting as that sounds.

There are many reasons as to why a dog might eat his poop, be it his own, or someone else’s :

The dog is missing something from its diet, and is looking to regain enzymes or minerals it is lacking. Some dogs are also missing fiber in their diets.
The dog is hungry, either due to lack of food, or internal parasites, such as worms. If the dog eats too quickly, then he may crave his nutrient rich poop. Or if the dog has digestive problems, and his food is not being properly absorbed.
The dog is either bored, lonely, anxious or stressed.
The dog may eat his poop to clean up his area, especially if he poops in his crate or bed.
The dog may eat his poop to hide the ‘evidence’ if it knows it will anger you.
If the dog is a female, it is natural for her to eat her offspring’s poop to keep the den clean, and to ward off predators, so eating her own poop, or a housemates’ poop might be natural for her.
If your dog is an older unneutered male, or a male who was neutered late in life, he may eat other dogs’ poop to try to establish ownership of territory.
Some dogs eat poop just because they love the taste of it.
Some puppies eat poop as a novelty. The smells may be intoxicating (in a good way) to the pup. Puppies are also very curious by nature, and they love to get into things that are new. Puppies also love what is familiar to them, and a fresh poop can seem very similar to what his mother fed him when he was a tiny puppy, when she regurgitated food for him.

Now that we’ve covered the reasons why a dog may eat his own, or other dogs’ poop, we’ll go over how to stop him from doing so. If he’s eating his own poop, there shouldn’t be any danger to the dog, but if he’s eating other dogs’ poop, then he may pick up some unwanted parasites. All that and the
fact that as people, we just find it plan gross!

When it comes to treating any unwanted behaviors, the best course of action is always prevention, and regaining control of the dogs’ environment. We want to set the dog up to succeed, so we will try to prevent him from doing it in the first place. The best way to do this is to keep the dogs’
area clean. Do not leave him enough time alone with his poop so that he has time to wolf it down. Clean up after him right away. You can also keep him on a leash, so that he is not allowed to get near ANY type of poop.

You can then offer him a better course of action. One that will reward him more than his poop eating, as he finds his poop eating to be a VERY self rewarding behavior. He wouldn’t do it if it didn’t reward him in some way. All we have to do is find out what is more rewarding to him.
That may be a change in diet, a deworming, more exercise, neutering, more people/dog time, or rewards that are much yummier than doggy poop!

I would not suggest using any negative forms of punishment, such as yanking on his collar or leash when he tries to eat poop. A voice command may work, but luring him away with a much better smelling, yummier treat will get a better result! The dog will choose whatever pays off the best! Teaching the dog the ‘off’ or ‘leave it’ command can also come in very handy here.

There are also consumable deterrents you can use too. Pet supply stores and your vet carry products for this purpose. You can also put one of the following into the dogs’ food that should render his poop not so tempting anymore. Adding cooked spinach, pumpkin or meat tenderizer should help with
this.

All in all, the deterrents should work, but dealing with the source of the behavior will yield in much better results. So long as you practice diligence and consistency, you should be able to help your dog to give up his dirty little secret!

Good luck and happy training!
