As of Tuesday, Petco says they no longer sell electronic "shock" collars and have removed them from its shelves and website.The company said they stopped selling the human- and bark-activated electronic pet collars in a press release on Tuesday because they wanted to strengthen their commitment to positive reinforcement training methods. They also wanted to solidify their evolution from "a leading pet specialty retailer to a category-defining health and wellness partner" for animals and their owners."Electricity may be critical to powering your microwave, but it has no role for the average pet parent training their dog," said Petco CEO Ron Coughlin in the press release. "Shock collars have been shown to increase fear, anxiety, and stress in dogs, and we believe there's a better way – Positive Reinforcement Training."The San Diego-based company is also calling on the pet industry and consumers to join in its newly launched "Stop the Shock" online campaign that will create "responsible regulation for the retail sale of shock collars to general consumers."Along with today's announcement, Petco also launched a new look declaring itself "Petco, The Health + Wellness Co." to reflect how they've evolved into a health and wellness company."As a health and wellness company, our mission is focused on improving pet lives, and we think selling shock collars does the opposite," Coughlin said in the news release. "It's our responsibility to ensure that we, and others, aren't putting potentially harmful products in the wrong hands." 1551

As wildfires rage across the western part of the country, firefighters are doing their best to contain the flames and prevent further devastation. Most of the fires are burning in areas that haven't seen a wildfire in a long time, making the loss of life and land even worse."It's been difficult. This is becoming all too common. Another record-breaking, severe, unprecedented fire season here in Colorado. And this was the largest forest fire in the White River National Forest history," said Forest Supervisor Scott Fitzwilliams, speaking about the Grizzley Creek Fire. Fitzwilliams says not all wildfires cause complete destruction. In fact, many provide some crucial ecological benefits. Take the big horn sheep who live in the forest. "Their defense mechanism is those big eyes on the sides of their heads so they can see predators coming. And so, they will abandon a habitat when there's too many trees and too much brush and so in many areas of the canyon, this fire improved big horn sheep habitat," said Fitzwilliams.The Grizzly Creek Fire also burned the top of a canyon, helping the habitat for elk and deer. A silver lining to the Grizzley Creek Fire, which also charred creeks that provide drinking water for an entire town in Colorado and was unexpectedly slowed by an early snowfall in the area.At Sequoia and Kings Canyon National Parks in Central California, fire officials conduct what they call "prescribed burns.""A prescribed burn is literally us giving a prescription to the forest," said Mike Theune, Fire Information Officer for Sequoia and Kings Canyon National Parks. Prescribed burns are slow and steady, clear out unnecessary brush and naturally revitalize a forest, he says.Theune and Fitzwilliams say, for more than 80 years, fire services across the country used to put out any and all fires, even if they occurred naturally, such as from lightning."[In the] early 1900s when forest service came into view and smokey bear and we thought we needed to put out all the fires and we did. And we did a great job of it and Smokey Bear was the best spokesperson we could ever ask for but what that did is significantly change the landscape as far as the density of vegetation," said Fitzwilliams."We need to restore that ecosystem to what those natural levels are and one of the ways we can do it is through a very measured and very managed scientifically based approach to prescribed burning," said Theune.Theune says not all national forests in the country need prescribed burns as there are some states that deal with too many forest fires. National parks and forests officials say it's important to evaluate each individual ecosystem's needs in order to preserve their beauty for years to come. 2730

ATLANTA, Ga. – The Centers for Disease Control and Prevention (CDC) is warning parents to be on the lookout for symptoms of acute flaccid myelitis (AFM) in children.The public health agency said Tuesday that it anticipates that 2020 will be another peak year AFM, an uncommon but serious neurologic condition that affects mostly children.AFM can progress rapidly over the course of hours or days, leading to permanent paralysis and/or the life-threatening complication of respiratory failure in previously healthy patients, so it’s important to seek medical care as soon as possible.The disease has peaked every two years between August and November in the U.S. since 2014, when the nation experienced the first peak of 120 cases, according to the CDC. There were also peaks in 2016 and 2018.The third and largest peak of AFM occurred in 2018, with 238 cases in 42 states. Most cases were in children (94%) and most patients (86%) had AFM onset during August through November. Most patients had a fever and/or respiratory illness approximately six days before limb weakness onset. Other common early symptoms were difficulty walking, neck or back pain, fever, and limb pain.The CDC says parents and doctors should suspect AFM in patients with sudden limb weakness, especially during August through November. Recent respiratory illness or fever and the presence of neck or back pain or any neurologic symptom should heighten their concern.Experts say enteroviruses, particularly enterovirus-D68 (EV-D68), are likely responsible for these peaks in cases. EV-D68 is the most common virus identified among specimens collected from patients with AFM. However, other viruses can cause AFM and may also be contributing to the biennial peaks.Although AFM symptoms resemble those of polio, all specimens have tested negative for poliovirus.There is currently no specific test, proven treatment or prevention method for AFM.“As we head into these critical next months, CDC is taking necessary steps to help clinicians better recognize signs and symptoms of AFM in children,” said CDC Director Robert Redfield, M.D. “Recognition and early diagnosis are critical. CDC and public health partners have strengthened early disease detection systems, a vital step toward rapid treatment and rehabilitation for children with AFM.”AFM and COVID-19The CDC says AFM is a medical emergency and patients should seek immediate medical care, even in areas with high COVID-19 activity.It’s not known how the COVID-19 pandemic and the social distancing measures may affect the circulation of viruses that can cause AFM, or if COVID-19 will impact the health care system’s ability to promptly recognize and respond to AFM.There is one bright side. If social distancing measures decrease circulation of enteroviruses this year, AFM cases may be fewer than expected or the outbreak may be delayed.Learn more about AFM here. 2901

As the nation continues to face a shortage of nurses, parents in Chicago say they’re feeling the effects particularly hard when it comes to their children’s public schools.Mason Rodriguez is a smart, gregarious 6-year-old boy, who enjoys going to school. When he comes home each day, his mother, Laurel Henson, asks if he had daydreams. That’s because Mason has epilepsy, and the word daydreams is used to describe his seizures.Henson says her son’s seizures are getting worse.“He has them every couple days,” Henson says.Mason’s school has no dedicated nurse, and the medication he’s been given in the event of a serious seizure is not something a teacher can administer. “The issue is they have no one on staff at the school, obviously because there’s no nurse to administer the medicine, because it has to be done rectally and they have to be certified,” Henson explains.As a result, Henson says the school told her that in an emergency, they would call 911. But she worries officials wouldn’t get there fast enough.“For the district rep to say, ‘Were not a Band Aid service,’ it’s like, this is not a Band Aid issue. This is my kid’s life, and there’s other kids, ya know?” Henson says.According to the American Nurses Association, the nationwide nursing shortage is so bad that by 2022 there will be more registered nurse jobs available than any other profession.The shortage has hit Chicago Public Schools particularly hard. A million plan--put forward and passed by the Board of Education just this week--aims to add more nurses to the district’s schools, including Mason’s. But not all parents see this as the solution, because the nurses would be temporary.“People from temp agencies have come in untrained, unreliable,” says Wendy Katten.Katten is with Raise Your Hand for Illinois Public Education, an education advocacy group made up of parents. She says there are only 100 certified nurses, and Chicago has over 500 schools. Some parents have now left jobs to be at school with special needs kids.“There are three federal laws that you know are in place to protect children, and those laws aren’t being followed,” Katten says. “The fact that parents are sitting in schools missing work, not getting a pay check because the district is violating, you know, laws, is outrageous.”Chicago Public Schools declined our requests for an interview, but sent us a statement saying, in part, they’re also hiring “20 board employed nurses…” and that they’re working to “ensure every student receives the support and services they need…”“Ensuring greater consistency in nursing services is a top priority for the district, and we are working to strengthen staffing by hiring an additional 20 board-employed nurses and expanding the pool of available vendor support. We will continue working with schools and families to gather feedback and ensure every student receives the supports and services they need to access a high quality education,” read part of the statement.Henson thinks temporary nurses could definitely help her son, but she says it isn’t a long-term fix. 3122

As the debate over arming teachers in schools reverberates across the country, Kansas is doubling down on the idea.A new bill would not only authorize the arming of Kansas school staff, it would hold schools responsible if a shooting were to occur and the teachers and staff present were not allowed to be armed.Here's the exact wording?from House Bill 2789:"In any action against a unified school district arising out of acts or omissions regarding the possession or use of firearms on the premises of such school district, there shall be a rebuttable presumption of negligence on the part of such school district when it is shown by evidence that such school district did not authorize any employee of such school district, other than school security officers, to carry concealed handguns..."The House bill is causing some serious contention in the Kansas state capitol. During a House Insurance Committee hearing on Tuesday, Rep. Blake Carpenter, one of the bill's authors, quoted the movie "American Sniper" and said violence in school was a matter of "when" and not "if.""It's not if our kids will be killed; it is when they will be killed and what we are doing to prevent it," he said,?according to the Kansas City Star.CNN has reached out to Carpenter for comment.The bill has received significant pushback. A group of protesters was present at Tuesday's hearing, and Rep. Brett Parker, a Democratic opponent of the bill, shared a photo of stacks of papers he says are written testimonies against it.Kansas teachers?are technically already allowed by state law to carry guns on public school campuses as long as they have a permit and meet any school-specific requirements. But according to the Kansas City Star the 2013 legislation caused problems with insurance providers for some of the state's school districts, who refused to extend coverage because of the liability of armed staff.As a result, some districts put their own policies in place, overriding the law and disallowing the concealed carry of weapons on school property.The bill currently before the House committee also addresses this by forbidding insurance companies from refusing coverage just because a school district allows teachers and staff to be armed."No insurance company shall charge unfair discriminatory premiums, policy fees or rates for, or refuse to provide, any policy or contract of real or personal property insurance, liability insurance or policy containing liability coverage for any unified school district solely because such school district authorizes employees of such school district to carry concealed handguns on the premises of schools and attendance centers operated by such school district..." the bill states. 2742
