Is the quality of dog semen declining? And are contaminants in dog food to blame?


Researchers at the University of Nottingham say they’ve documented a serious decline in the fertility of male dogs — and suggest that dog food or environmental causes may be to blame.

In a study spanning 26 years, researchers tracked the sperm motility levels of five different breeds — Labrador retrievers, golden retrievers, curly coat retrievers, border collies and German shepherds.

They took samples from between 42 and 97 dogs each year, according to the study, published in Scientific Reports.

Between 1988 and 1998, the team recorded a 2.5 percent decline in the amount of motile sperm per year. Between 2002 and 2014, this trend continued at a rate of 1.2 percent each year.

The researchers also found that male pups produced by dogs with declining sperm quality had an increased incidence of cryptorchidism, a condition where one or both of the testicles don’t descend properly.

The study suggests that the sperm quality may have been impacted by contaminants in dog food.

“We looked at other factors which may also play a part, for example, some genetic conditions do have an impact on fertility,” said Dr Richard Lea, leader of the study. “However, we discounted that because 26 years is simply too rapid a decline to be associated with a genetic problem.”

Dogs used for the study were all bred, raised and trained as service animals for disabled people at an unidentified center in England, according to the New York Times.

The scientists said that in addition to collecting samples throughout the study, they examined the testicles collected from dogs that had undergone castration.

Both showed environmental contaminants in high enough concentrations to affect sperm motility. These same chemicals were also discovered in various commercially available dog foods.

The researchers say the findings raise the question of whether a reported decline in human semen quality over the last 70 years could also be a result of environmental factors.

Program works with Amish in southern Indiana to improve breeding conditions

odonamish

While Amish breeders are notorious for running puppy mills, some of those in southern Indiana are working with Purdue University’s Center for Animal Welfare Science to improve their breeding practices and, in the process, their reputations.

“It was time that we as breeders recognize that there are professionals out there that can help us and we need to involve them in our businesses,” said Levi Graber, a member of Odon’s Amish community who helps several breeders in the area.

Though the Amish aren’t known for reaching out, or letting people in, Graber contacted the university a few years ago about improving Amish-run breeding operations in the region. That led to a pilot program in which the operations are reviewed, and suggestions are made on how to improve them.

Already, those behind the program say, they’ve found that improving conditions and practices at the kennels leads to happier, healthier, better behaved dogs.

Under the program, which is open to non-Amish breeders as well, a set of voluntary standards will be created for breeders to follow, according to the Lafayette Journal & Courier.

“Many folks hear about breeding and animal welfare and they don’t know what (breeders) actually do. They just want to put them out of business,” said Purdue’s Candace Croney, director of the animal welfare center.

Most dogs she and her team of researchers have observed have been in good physical health, Croney said, but some had room for improvement in their behavior. Some facilities’ dogs were loud and dogs became over-excited when they saw people, which Croney said indicated they weren’t used to seeing people often.

The research team advised those breeders to make sure something positive happens for the dogs, such as receiving a treat, every time someone comes into the kennel area. They also suggested letting the dogs out in the yard daily to exercise and socialize.

The changes made a big impact, Croney said. Over four months, the dogs in the kennel with the most behavioral issues became calmer when they saw people, and they physically looked better.

“We’ve seen a very positive impact on some of the things she recommends,” Graber said. “I’ve seen more contented, happy dogs.”

Once the trial program is complete, a third party will audit the breeders’ practices, Croney said.

Breeders who qualify will receive a certification that she said goes beyond the standards mandated by the U.S. Department of Agriculture, which cover areas such as housing, sanitation, food, water and protection against extreme weather and temperatures.

Graber said the community feels fortunate to work with Purdue and emphasized that the breeders don’t want to sell puppies that disappoint anyone.

Not all Amish-run breeding operations are like those that end up on the news, noted Dale Blier, who works for Blue Ribbon Vet & Supply in Odon and sells supplies to many breeders in town.

“The majority of dog breeders in Indiana treat their dogs the same way they treat making furniture: They want to be the best at it they can,” he said.

Two hearts beating as one? Study suggests, with dogs and owners, it’s almost true

Even though this may be more marketing than science, we can’t help but like the results of this experiment in Australia.

Researchers, in an experiment funded by Pedigree, found that not only do our heart rates lower when we and our pets are together (as everybody knows by now), but they begin to mirror one another.

True, only three dogs and owners were involved in the study. True, the main interest of the company that sponsored it is to sell dog food. And true, what’s new about their findings — how closely the heart rates align — is probably of more poetic than practical use.

But still … It’s good to have a little science (if it can be called that) confirm our feelings of being in sync with our dogs.

In the experiment, three Australian dog owners separated, and then reunited with their pet in a staged but homey setting to see what kind of effect they had on each other’s heart rate.

Both dogs and owners were equipped with heart monitors.

“There was a really strong coherence in the heart rate pattern of both the owner and dog. Upon being reunited within the first minute, each heart rhythm became almost directly aligned and we saw a reduction straight away,” Mia Cobb, canine scientist and demonstration co-conductor told The Huffington Post Australia.

“This project is a really good illustration of what most owners experience every night when they come home from work and are reunited with their companion,” she added.

Have you hugged your dog today?

????????

We’re not recommending you do, and we’re not recommending you don’t. We’re only taking a quick look at the subject because, pure and innocent an act as hugging your dog might seem, it is not without controversy.

Stanley Coren, author of many dog books, stirred up a little of it in his column this month for Psychology Today, citing “new data” that shows getting hugged raises the stress and anxiety levels of dogs, and the possibilities of someone getting bitten.

Some people who have been hugging their dogs for years (and insist their dogs enjoy the affection) found his conclusions laughable, labeled him a party-pooping old fuddy duddy, and said his research techniques were anything but scientific.

We’d agree only with that last part — because Coren’s “new data” was gathered by looking at 250 random photos on the Internet of people hugging dogs.

“I can summarize the data quite simply by saying that the results indicated that the Internet contains many pictures of happy people hugging what appear to be unhappy dogs,” he wrote.

“In all, 81.6% of the photographs researchers scored showed dogs who were giving off at least one sign of discomfort, stress, or anxiety. Only 7.6% of the photographs could rate as showing dogs that were comfortable with being hugged. The remaining 10.8% of the dogs either were showing neutral or ambiguous responses to this form of physical contact.

doghug1Those signs of stress or discomfort include baring of teeth, lowered ears, a dog turning his head away, and a dog who either closes his eyes or shows what is called “half-moon eye” or “whale eye.”

That’s when you can see the white portion of the eyes.

Here’s the problem, though — or one of them, anyway. How does Coren, or anybody else, know that the dogs pictured are stressing out because of the hug. Couldn’t it also be a reaction to WHO is hugging them? Or a reaction to the camera?

The simple fact is some dogs like being hugged, some tolerate it, and others don’t like it at all.

For the latter group, it might be the amount of pressure applied during a hug that they are reacting to — enough to make them feel restrained. It might be that hugs tend to be spontaneous and come out of nowhere.

Then, too, mood could be a factor. Sometimes dogs, and humans, feel like being hugged and sometimes they don’t.

There are just too many variables to make a sweeping conclusion — especially when it’s all based on what photos turn up in your Internet search and your subjective interpretation of those photos.

doghug3Reading a dog’s emotions is tricky enough when you are face to face with one. Doing it from a photo is even more problematic. What for example is this dog thinking?

Hard to read emotions through that many wrinkles, but he seems to be digging it.

We’d agree with the experts who say hugging a dog you don’t know or have just met is not a good idea — and that children should be taught that early on.

But beyond that, we’d be hesitant to put the kibosh on dog hugging altogether, especially when it’s based on Flickr’ed or Facebook’ed photos posted by dog owners wanting to show how much they love their dogs — whether their dogs like it or not.

In this writer’s life, he has been creeped out by some hugs, tolerated others, found some both warm and comforting, and gotten truly enthused by a few.

Probably, some old photos exist of him showing half moon eyes while being squeezed by his big sister.

Does that mean he doesn’t like hugs?

Of course not. He just prefers to make the decision on a case by case basis. Dogs should have that freedom, too.

Dangling dog rescued from 13th story window in Bogota — the hard way

A man’s daring rescue of a dog hanging out the balcony window of a 13th floor apartment in Bogota, Colombia, was caught on video.

The video was posted earlier this week on the Facebook page of Love for the Animals, an animal rights group in Bogota.

The dog, named Luna, had apparently gotten stuck between the rails that covered the window, with most of her body hanging out the window.

Luna’s owner wasn’t home so the only way to get to reach her was from the outside.

Diego Andrés Dávila Jimenez first tried to use a broom to push the dog back inside, while leaning out the window of an apartment one floor below. When that didn’t work he climbed one story up the face of the building as a crowd below watched and shouted encouragement to him.

“People on the ground were screaming. They had a mattress out just in case,” said Jimenez, according to The Dodo. “The truth is, I did not think about the dire consequences. I did not look down.”

Jiminez climbed up the building, over the rails and into the apartment, then pulled the dog to safety.

“When I had Luna in my hands and looked down, a thousand thoughts flew through my mind,” Jimenez said. “My girlfriend was a little upset, yelling at me ‘You stay there! Do not climb back down!'”

When Luna’s owner came home and found out what happed, “she was in tears,” Jiminez said. “She is very grateful, because she just adores that dog.”

Making New Year’s resolutions for our dogs is more popular than ever, survey finds

new-years-dog-3

A survey conducted for Milk-Bone says more Americans than ever are including their dogs in their New Year’s resolutions.

To which dogs, could they respond, would probably do so with a sarcastic “Gee, thanks.”

But fret not canines. Putting you on a diet ranks all the way down at nine in the top 10 list, and the most popular resolutions are mainly ones dogs would wholeheartedly support.

And keep it mind, we humans hardly ever carry out our resolutions, anyway.

Three thousand pet owners were surveyed, and the most popular resolutions were:

1. I will spend more time with my dog. (52%)

2. I will help my dog to have better health and wellness. (42%)

3. I will take my dog on more trips with me. (34%)

4. I will brush my dog’s teeth regularly. (31%)

5. I will help my dog get essential vitamins and nutrients.(30%)

6. I will help my dog become less anxious and stressed. (29%)

7. I won’t feed my dog food from the dinner table. (25%)

8. I won’t leave my dog home alone for quite so long. (23%)

9. I will help my pet lose weight. (21%)

10. I will take my dog to dog training class. (15%)

Black lab has Michael Jackson’s disease

rowdy

Rowdy has been poisoned by river water and shot by police officers, but it’s a far less threatening skin condition that gives the 13-year-old black Lab his unique look

Rowdy has vitiligo, a disease whose most famous victim was Michael Jackson. In Rowdy’s case, it causes him to lose color in different patches on his body.

rowdy2Rowdy has lost the color pigmentation around his eyes, making him look like he’s wearing a mask.

“He’s like our own little celebrity around town,” Rowdy’s owner, Tim Umbenhower told KPTV. “Everybody loves to stop us and wonder what we did to him or if we painted it on there.”

Umbenhower and his wife Niki, who livein Canby, Oregon, say Rowdy survived poisoning by river water and had to have his stomach pumped.

He was also once accidentally shot by police during what they thought was a burglary.

Niki, on her Facebook page, mentions the possibility of appearing on The Ellen Show and in a movie — and while she might just be joking, stranger things have happened.
