Aiming high to leave their mark

39384407 - dog

No matter how big your male dog is you’ve probably noticed, and maybe wondered why, when he finally finds what upright object he wants to pee on, he often strains to aim as high as he can.

The answer is — and perhaps this is more a matter of male behavior than canine behavior — he’s trying to impress other dogs.

canine_urine_marking_dog_behaviorScience and conventional wisdom generally concur that sharing urine scents serves to let dogs get to know each other — that it’s a method of honest communication.

But now a group of researchers is saying that — honest as it otherwise is — there is some deception going on, especially along smaller dogs who are even more likely to hike their legs as high as they possibly can to leave the impression that they’re bigger than they really are.

In a study published in the Journal of Zoology, Betty McGuire and her team at Cornell University found smaller dogs tend to urinate more often than larger dogs, and they’re more likely to aim higher when focusing on vertically oriented targets.

The researchers went so far as to follow adult male dogs while they (the dogs) urinated on walks, then calculated the angle of their legs when raised during marking. They (the researchers) compared those calculations to the dogs’ height and mass and measured the height of the urine marks on the dogs’ chosen targets.

“Small males seemed to make an extra effort to raise their leg high — some small males would almost topple over,” McGuire told New Scientist. “So, we wondered whether small males try to exaggerate their body size by leaving high urine marks.”

The researchers said it’s likely the goal is to deceive other male dogs, but I suspect it is to impress the ladies, too.

But, I’d argue, neither is limited to canines.

Go to any bar and you can see pretty much the same thing, minus the fire hydrants, lampposts and urination, but with the same kind of loudness, strutting, poking out of chests, boasts, and little white (or yellow) lies.

Seems that, when it comes to the male of the species, neither dogs nor humans are above a little showing off.

When your dog tells you you have cancer

taffyFour years ago, Nancy Granato was sitting at home in Pitman, N.J., with her granddaughter’s dog on her lap.

Suddenly the shih tzu began going in circles, nudged her in the left breast, then got down on the floor and howled.

It was unusual in several ways. For one thing, Taffy never barked.

Granato, as the dog continued yapping, reached for the spot Taffy had nudged and found a lump.

She visited doctors, had some tests done, and was told she had nothing to be concerned about. To be safe though, she underwent a biopsy. It confirmed what she suspected Taffy was trying to tell her — she had breast cancer.

“I did listen to the dog, but I also listened to me,” she told the South Jersey Times.

The ability of dogs to detect cancer is well documented, if not completely understood. But it’s unusual for one who hasn’t been trained to do so to make what seems to be a diagnosis.

 Researchers believe what dogs are smellling are the chemical changes that occur when normal cells are altered by cancerous ones.

Granato found out she was in the first stage of breast cancer. Doctors removed the lump and she underwent chemotherapy. During her treatments, Taffy provided some emotional support, she said.

Granato said she has been in remission for four years. Doctors detected another lump last September, but she says she wasn’t too worried.

“I kept saying, ‘The dog didn’t bark,’ ” Granato said. “It can’t be.”

Results showed the lump was benign.
