DEAR READERS: Please see the following post from veterinarian Dr. Bob Goldstein via EarthAnimal.com:

"Recently, there have been reports in several European countries of dogs developing 'Werewolf Syndrome.' While not a recognized medical condition, it causes neurological symptoms such as aggression, excessive barking and agitation, howling, restlessness, excessive chewing and even more serious symptoms such as vomiting, diarrhea and seizures. When grouped together, these symptoms align with the category of inflammation affecting the brain and nervous system.
"In the UK, the Food Standards Agency (FSA) is advising pet parents to immediately stop giving these (rawhide) products to their pets and to closely monitor them for any unusual behavior or neurological symptoms (see food.gov.uk/news-alerts/news/precautionary-advice-issued-to-pet-owners-on-dog-chews-linked-to-illness). More specifically, the FSA is urging consumers to stop purchasing Barkoo and Chrisco rawhide products, which are available online. Additionally, if a dog exhibits any concerning symptoms, the FSA strongly recommends seeking prompt veterinary care.
"The category of rawhide chews and treats has long been a topic of controversy due to the processes involved in their production. Rawhide chews are a byproduct of the leather industry, where a cow’s skin is split -- the upper layer is used for leather, while the lower layer is processed into dog chews. However, the methods used to store, process and preserve rawhide are widely debated, particularly concerning the use of chemicals such as formaldehyde and bleach, which have raised concerns about the impact of rawhide chews on a dog's health.
"The most popular advantage of rawhide chews is their long-lasting nature, which helps exercise a dog’s teeth and gums while also reducing boredom. However, the potential side effects, along with the risks of choking and intestinal blockages, require careful consideration."
DR. FOX HERE: Regarding the symptoms Goldstein mentions, I suspect possible cadmium poisoning. Many countries -- including China, by far the biggest producer of cattle hides -- use trivalent chromium salts, vegetable tannins, synthetic tanning agents, aluminum sulfate and various additives to tan hides. Rawhide dog chews are processed with chemicals like sodium sulfide, lime, chromium salts, bleach and hydrogen peroxide to preserve them and enhance their flavor, and traces may remain even after washing.
FRESH WATER DAILY FOR PETS
An often-neglected part of responsible companion animal care is the daily provision of fresh drinking water, ideally filtered and purified. I use a ZeroWater filter for my municipal tap water, which is sourced from the agriculture-polluted Mississippi River.
Water bowls should be cleaned out daily to remove the bacterial biofilm that develops within hours of animals drinking and putting bacteria and food particles from their mouths into the water. Many dogs and cats are taken to emergency veterinary clinics, at significant cost, because of diarrhea caused by bacterial infection. Providing purified water in clean bowls daily could help reduce this health crisis. For more details, go to: drfoxonehealth.com/post/pure-water-for-cats-and-dogs-and-all.
Regarding fluoridated water, I agree with R.F. Kennedy Jr. that adding fluoride to municipal drinking water needs close review (as I posted years ago: drfoxonehealth.com/post/fluoride-in-pet-food-a-serious-health-risk-for-both-dogs-and-cats). I part company with him regarding vaccinations, especially against measles, which should be mandatory for children going to school -- just as vaccinations for a related virus, distemper, should be mandatory for all puppies to create a community or “herd” immunity. Unvaccinated human and canine survivors of such infections can have permanent neurologic and other health problems.
But I join him again on the issue of "azo dyes" and other chemical coloring agents being added to foods, against which I railed in my book “Not Fit for a Dog: The Truth About Manufactured Cat & Dog Foods,” co-authored with two other veterinarians.
There are alternatives. In an online statement, food additive company Oterra says, "By leveraging natural pigments like turmeric, Hansen sweet potato, etc., brands can create visually appealing, stable, and regulatory-compliant products that meet pet owners’ growing expectations.” (For details, go to: oterra.com/application/pet-food.)
Another benefit to plant-based dyes: easier carpet cleaning when pets vomit! Synthetic chemical coloring agents, some of which are carcinogenic, often leave permanent stains.
