The supply of Immiticide (melarsomine dihydrochloride), the only drug approved to treat heartworm infections in dogs, has been low since December 2009, but now it’s completely gone. Merial confirmed that it was officially out of the drug on August 9, 2011. The current situation is due to a new and separate manufacturing challenge related to technical issues with the company who provides the finished product, according to a Merial spokesperson. Merial said the company is working hard to make the drug available again, but cannot speculate when that might happen.

As we reported in Whole Dog Journal in March 2011, there is now ample evidence that at least one strain of heartworms has developed resistance to some of the market's best-known preventives. In addition, there is evidence to suggest that one of the most popular heartworm preventives, Heartgard, has an efficacy rate of less than 100 percent. The U.S. Food and Drug Administration's Center for Veterinary Medicine has sent at least one warning letter to Merial, the maker of Heartgard, asking the company to stop claiming 100 percent effectiveness for heartworm prevention. Given these developments, what should responsible dog owners do differently to better protect their dogs? The answer depends a bit on where you live and what you've already been doing to prevent heartworm infection.

The lawsuit filed by Kari Blaho-Owens, PhD, against Merial, her former employer, contains a number of serious allegations regarding Heartgard’s decreased efficacy and Merial’s knowledge of the problem.We may never know whether all the details alleged in the suit are true. It might take years in court – or it might be settled out of court. But the suit makes for fascinating reading.

Purchasing veterinary medications such as heartworm preventatives online can offer significant cost savings, but how can you be sure that you're buying the real thing and not counterfeit products from China, which can be impossible to tell apart? I recently read about a dog who tested positive for heartworms despite being given monthly preventative medications. The reason may be that the heartworm preventative the owner purchased online was not what it claimed to be.

Pfizer has announced plans to discontinue manufacture and sale of its flea and tick control product, ProMeris. Orders will continue to be filled until September 20, 2011. ProMeris was introduced in the fall of 2007, and touted as the first topical product to use metaflumizone. Pfizer gained control of ProMeris when it acquired Wyeth/Fort Dodge Animal Health in 2009. Pfizer is also the maker of Revolution, used to control fleas and one species of ticks, along with heartworm, ear mites, and sarcoptic mange.

On December 1, 2009, Merial published an open letter to veterinarians, announcing a shortage of Immiticide (melarsomine dihydrochloride), the only drug licensed for use in treating heartworm infestations in dogs. The shortage is due to a manufacturing site transfer. The company expressed hope that the shortage will not persist beyond the first quarter of this year.

Pain may be the most enigmatic of all the disease symptoms of man or beast. It is a sensation we all have experienced at one time or another and in varying degrees. But, few of us can explain adequately how a particular pain feels, fewer still can give a reasonable explanation for why pain occurs; and despite all the recent scientific research that has gone into pain, we still have a minimal understanding for how it occurs – or truthfully, for how to consistently prevent or alleviate it.

Ten years ago, my dog Piglet woke me in the middle of the night, trembling violently and utterly terrified. It took me hours to track the source of her panic to a barely audible high-pitched beep that sounded once every two minutes, coming from a smoke alarm’s low battery indicator. Behavior-altering drugs can help dogs with phobias or anxiety disorders but you have to learn which ones work best in each case.

Corticosteroids are perhaps the most enigmatic of all the drugs in the western medicine man's arsenal. It has been said by many practitioners that they are the most used and most abused of all our medicines. Corticosteroids are a necessary component of a healthy physiology and they can be life saving ... or they can cause multiple adverse side effects that can be devastating to a dog's health and well-being.

A holistic veterinarian warns dog owners about casual or sloppy use of synthetic antibiotics, and what the consequences could be for your dog, and even you! Every year we are literally dumping millions of tons of antibiotics into our living environment – each ounce of antibiotic with the potential to create yet another antibiotic-resistant strain of bacteria.
