A new dog poop solution — zap it to ashes

Forget that better mousetrap. Many of our planet’s best minds are now wrapping themselves around the issue of dog poop.

And here’s one of the latest devices destined for the market: The AshPooPie, a name that somehow (at least to me) sounds even funnier when a person with a British accent is saying it.

The AshPooPie was invented by Hebrew University of Jerusalem scientist Oded Shoseyov as a more environmentally friendly alternative to sending poop in plastic bags to landfills.

The AshPooPie is an easy to carry “wand” that allows you, with the push of a few buttons, to capture a pile of poop, then, through chemically induced incineration, turn it into a small pile of sterile and odorless ash .

Like fairy dust, almost.

The device is will be distributed by an Israeli company, Paulee Clean Tech.

“The amount of ash is between 10-20 per cent of the ‘original portion’ and it can blow in the wind like cigarette ash,” said Oded Halperin, a spokesperson for Paulee Clean Tech.

Scientist has high hopes for Chemspay

An Arizona scientist trying to induce menopause in mice — the female of that species up to then had been missing out on that experience — has discovered a pill to sterilize dogs, one she says could eventually bring an end to surgical spaying.

Dr. Loretta Mayer was looking for a way to artificially induce menopause in mice so they could be used to study human diseases when she and another scientist developed a drug that they realized also could be used to sterilize female dogs, the Arizona Republic reports.

If approved by the FDA — a prospect that could take years — Chemspay, as it has been dubbed, could revolutionize veterinary medicine and go along way in reducing canine overpopulation in Arizona and nationwide, Mayer says.

ChemSpay can be administered by either a pill or injection.

Mayer hopes to eventually introduce the drug in Arizona and recently persuaded the state legislature to alter state law to allow animal shelters to use non-surgical means for sterilizing cats and dogs.

Mayer, 62, spent more than 20 years working in business before returning to school to pursue a master’s and doctorate in biology at Northern Arizona University. In 2000, she began her postdoctorate work at the University of Arizona, working under Dr. Patricia Hoyer, an ovarian toxicologist who was studying diseases common in aging women.

Mice, unlike women, never lose their reproductive capabilities. So Hoyer and Mayer developed a drug they dubbed “mouseopause” that induced menopause in female lab mice by eliminating eggs in the ovaries without surgery. The development allowed lab mice to be used as models for studying diseases associated with menopause.

In 2002, Mayer started a biotechnology company called SenesTech, studying how the drug could be used on other animals. She has tested it on animals in Indonesia, India, New Zealand and Australia and on the Navajo Reservation, at the request of the director of the tribal animal shelter.

“He said to me, ‘If you could do for a dog what you do for a mouse, I wouldn’t have to kill 400 animals a month,’ ” Mayer said.

Mayer and SenesTech administered the contraceptive to reservation dogs from 2004 to 2008.The trials proved that Chemspay reduced the number of eggs in the tested dogs significantly.

Last year, SenesTech became involved in a project that combines rabies vaccinations with fertility control for the feral-dog population in parts of India. Mayer will return to India this December to resume her work with the group.

Although Chemspay is about six to nine years away from being approved by the FDA, Mayer said she hopes to begin FDA-approved trials in about three years at the Second Chance Center for Animals in Flagstaff.

Mayer is not the first scientist to develop sterilizing drugs for animals. Neutersol, a sterilizing injection for male dogs, was approved by the FDA and tested in trials at the Arizona Humane Society a few years ago. It was taken off the market in 2005 because of a manufacturing disagreement and is now being marketed under another name. It is not currently available in the U.S.

Spay, neuter programs are paying off

Forty years of selling the public on spaying and neutering pets is paying off:

This year fewer than 4 million unwanted dogs and cats will be euthanized, down from as many as 20 million before 1970, the Associated Press reported this week.

That figure’s still nothing to brag about, but it’s a massive improvement, and a testament — not just to surgery, but to the work shelters, rescue groups and animal welfare organizations do to encourage adoptions.

Most animal experts, though, according to the AP story, believe spaying and neutering has played the biggest role in reducing the number of unwanted, euthanized pets.

Nearly every public shelter, private rescue or animal welfare organization in the country now donates money, space or time to low-cost spay and neuter clinics, and spaying and neutering, in addition to becoming a requirement for most adoptions, has become the law in some states, counties and cities.

Spaying and neutering have also become less traumatic — for pets and owners.

“Now they make a one- or two-inch incision and use self-absorbing sutures” that mean a much quicker recovery for the animals, said Stephen Zawistowski, science adviser for the American Society for the Prevention of Cruelty to Animals (ASPCA).

Zawistowski recalled when he got his first dog spayed 50 years ago, “she had an incision that must have been a foot long and was sewn up with what looked like piano wire.”

In addition to eliminating shelter kills, spaying and neutering can make pets easier to manage, less aggressive and healthier, said Andrew N. Rowan, president and CEO of Humane Society International and chief scientific officer for the Humane Society of the United States.

The first public spay and neuter clinic in the U.S., according to the AP story, was opened in Los Angeles in 1969.

What makes the figures all the more impressive is that the decline in the number of animals being euthanized each year comes even as the pet population has boomed. There were about 62 million companion pets in 1970, versus about 170 million today, Zawistowski said.

In years ahead, sterilizing a dog or cat may not always mean surgery. Work continues on pills, implants and vaccines that render cats and dogs unable to reproduce.

Dr. Gary Michelson, a billionaire orthopedic spinal surgeon and founder of Found Animals, posted a $25 million prize in 2008 for the creator of an affordable chemical sterilant, and has put up another $25 million for grants to scientists doing the research.

“When we first saw grant proposals coming in, we saw old ideas that had been laying around for 15 or 20 years. What we are seeing now are proposals based on cutting edge science — areas related to cancer and stem cell research. The level and sophistication of the science has moved to a higher level,” said Zawistowski, who is on the prize board.

In 2003, the FDA approved the first sterilant for male dogs. But at about $50 a shot, Neutersol was too costly. It was reworked, the price was cut to about $6 a dose and it was again approved by the FDA under the name Esterilsol. After trials around the world, it is expected to be available in the United States later this year.

Spurned and burned, Wolfie bounces back

About four months ago, two dogs were found wandering the streets of Phoenix, both with what appeared to be fresh and severe chemical burns on their backs.

One of them was a puppy, a pit bull mix named Ash, who was featured in news reports and, after medical treatment and some time in foster care, adopted out to a new home.

The other was this fellow to your left, a one-year-old pug mix who has also recovered from his burns — though his back, too, remains scarred  – but hasn’t gotten as much press as his partner.

Maybe it was because his pug-something mix didn’t have the media appeal of a pit bull. Maybe someone found his underbite, which makes him look a little like a miniature wolfman, camera-unfriendly.

When I ran into Wolfie, as he has been named, at an adoption event/fundraiser in Cave Creek, Arizona, Saturday, he seemed eager to flash his grin and happy to pose for my camera.

But, by weekend’s end and after appearing at two adoption events — one at For Goodness Sake, a thrift store in Cave Creek whose sales benefit animal rescue groups, another at an area pet store — Wolfie remained in need of a permanent home.

He’s an affectionate little dog who — though he still gets scared by strange objects and sudden motions — gets along well with both other dogs and humans, according to Paula Monarch, who’s serving as his foster mom through Little Rascals Rescue.

Wolfie has been in Paula’s care since September — about a month after he and Ash were found in South Phoenix, both with severe burns that were believed to have been caused by chemicals, acids or pool cleaners.

Officials suspect it was an intentional act, but no arrests have been made.

Wolfie spent three weeks at the vet’s, getting his wounds flushed and cleaned several times a day, and his burns coated in silver sulfide.

They’ve healed over and no longer cause him any pain, but because of the hairless streaks on his back, he’ll probably need to wear sun screen or a T-shirt if he spends much time outside.

Paula said she suspects Wolfie may have suffered other abuse, as well. He gets nervous when she picks up the remote control, and will scurry away with his tail between his legs.

Before long, though, he’s over it and cuddling again.

Already, the tale of Wolfie is a brighter one than that of a Phoenix, a pit bull who was set on fire in Baltimore last year. Despite a valiant fight, she died several days later, but her case led to an ongoing re-examination of how best to fight animal cruelty in the city.

Wolfie made no headlines, and he’s still waiting for that one person or family who see courage in his bald spots, beauty in his underbite, and will ensure the next chapter of his story is a happy one.

Toxic dumping turned Russian dogs green

greendogA pack of wild dogs roaming the outskirts of the Russian city of Yekaterinburg have taken on a green tinge, and authorities suspect it’s from scavenging for food in a dump that may be contaminated with chemical waste.

The greenish dogs are among a pack of about 20 strays, believed to be former guard dogs.

“I go past those dogs every day,” villager Alexei Bukharovsky told the Russian news agency RIA Novosti. “They are usually reddish … but then I saw, running along the white snow, an almost completely emerald dog. At first I thought someone had been playing a joke.” 

A police spokesman told the news service that illegal dumping of chemical waste is probably to blame. The spokesman said local councils had been ordered to clean up the site.
