riverbosun Posted July 24, 2012 Share Posted July 24, 2012 Took Coyote in for his annual today and Interceptor is still on back order. She offered Sentintal with Progam (flea product) for the same price as interceptor but I'm nervous about this. I opted to go with Heartguard temporarily. Anyone else continuing to have problems getting Interceptor and does anyone have experience with the Sentinal/Program product?

Hubcitypam Posted July 25, 2012 Share Posted July 25, 2012 (edited) Heartguard is NOT recommened for any greyhound (or sighthound). I would NOT give it, give the Sentinel. WHAT???? Never in my life have I heard that. If Ivermectin (active ingredient for heartworms) was bad for greyhounds, there'd be very few greyhounds alive. Both Dr. Stack and my old vet told me that a greyhound could eat several boxes of Heartgard with no ill effects. Heartgard is not recommended for collies, shelties,and some other herding dogs. What is the basis for your saying no Heartgard for sighthounds? ETA - I just googled and came up with two hits on Ivermectin being bad for greyhounds. One was the Comfortis website (imagine that) and the other was a chicken forum. Edited July 25, 2012 by Hubcitypam Quote Link to comment Share on other sites More sharing options...

I've never heard that about Heartguard. The active ingredient is ivermectin...what racing kennels use...what we've always used, except the year before I met Ken and used Sentinel Quote Link to comment Share on other sites More sharing options...

RaineysMom Posted July 25, 2012 Share Posted July 25, 2012 (edited) I've read it several times over the past few years and the vets where we take them say the same thing ... I guess there can be a bad reaction in some? At any rate, I would not give it and just give the Interceptor instead.

Hubcitypam Posted July 25, 2012 Share Posted July 25, 2012 I think your vets are just trying to sell you on the more expensive Interceptor. If you could post one or more of those articles maybe we (and our collective vets) could learn something. Quote Link to comment Share on other sites More sharing options...
Guest KennelMom Posted July 25, 2012 Share Posted July 25, 2012 (edited) But that's my point...WHAT RISK????? Any dog can have a reaction to any drug at any time. But that doesn't mean you never give them anything. Like Pam said, there wouldn't be many greyhounds around if Ivermectin were contraindicated in greyhounds. Collies and the like, yeah. I've definitely read that. But greyhounds? Or all sighthounds for that matter....no. Heartguard is fine for greyhounds. I'd be interested in reading documentation otherwise. Our vet, who has a very large sighthound practice (even above and beyond our own large crew) has no issues with ivermectin and, in fact, wrote us an RX for liquid ivermectin at one point.

KF_in_Georgia Posted July 25, 2012 Share Posted July 25, 2012 (edited) Some of the ivermectin heartworm meds can cause problems for collies and collie-crosses--not for greyhounds. Meanwhile, I'd love to buy the more expensive Interceptor...mainly because it's effective against a wider range of parasites than Heartgard Plus is. And Heartgard Plus gives both my dogs 24 hours of diarrhea. But my vet is still out of Interceptor, too.

JJNg Posted July 25, 2012 Share Posted July 25, 2012 She offered Sentintal with Progam (flea product) for the same price as interceptor but I'm nervous about this. I opted to go with Heartguard temporarily. Anyone else continuing to have problems getting Interceptor and does anyone have experience with the Sentinal/Program product? As others have mentioned, Sentinel is safe and a good product. However, keep in mind that Program is only a flea birth control (keeps eggs from hatching), so it won't kill adult fleas your dog picks up but will keep you from getting an infestation in your house. Because of the added flea ingredient, Sentinel is significantly more expensive than Interceptor. If your vet offered it to you at the same price, I'd jump on it. LOL Heartguard is NOT recommened for any greyhound (or sighthound). I would NOT give it, give the Sentinel. While it seems that some vets believe this, it is a myth and just plain wrong. There is no reason that Heartgard is unsafe for greyhounds, or any sighthound for that matter. Heartgard is even safe for collies and other herding breeds that are sensitive to ivermectin. The ivermectin-sensitive herding breeds have a specific gene mutation (MDR-1) that allows ivermectin to cross the blood-brain barrier into the brain and cause neurologic signs. However, this sensitivity is dose dependent, which means it only causes problems over a certain dose of ivermectin. The amount of ivermectin in heartworm preventative is tiny, and well below the toxic dose even for sensitive collies. A collie would have to eat 10-20 tablets of Heartgard to have a problem. I was curious about the origins of this unfounded myth about greyhounds/sighthounds and ivermectin, so I did a little research a while back. In the course of my research, I came across a post on a vet forum where a vet stated that her former boss "absolutely, positively insisted that sight hounds shouldn't get ivermectin." Another vet posted that "apparently sighthounds are closely related to the British herding breeds" and gave this link as a reference. This is what I posted in response: ----- I've been hearing reports of vets who are saying that sighthounds, or more specifically greyhounds, shouldn't get ivermectin. As someone who is involved in greyhound adoption, I know that this isn't true for greyhounds (most racing kennels use liquid ivermectin for heartworm prevention). I came across this discussion in my search to try to figure out the source of this information. From what I've been able to find, the only "sighthounds" that have been documented to have the MDR-1 mutation are long-haired whippets and silken windhounds. Both of these are fairly newly created, and somewhat controversial, breeds that go back to a whippet breeder who also had Shetland sheepdogs. He claimed that the "long-haired whippets" he produced were a throwback to a historic recessive gene for long hair in the whippet breed. Most in the whippet community feel that the dogs were whippet/sheltie mixes, and especially given the presence of the MDR-1 gene (and that long-haired purebred whippets don't exist), I'd say that makes more sense. Silken windhounds were created from a combination of borzoi, whippets, and long-haired whippets. Here are a couple articles I found that were of interest. However, I still don't know why some vets think that greyhounds can't tolerate ivermectin. http://www.pnas.org/.../11725.full.pdf http://www.ncbi.nlm....pubmed/20655253 ----- The articles above discuss breeds in which the MDR-1 gene has been found. It has not been identified in greyhounds or any other sighthound breed other than the above mentioned long-haired whippets and silken windhounds that are suspected to have sheltie in their background. As far as I'm aware, I believe all the track kennels use liquid ivermectin as heartworm preventative for their greyhounds. When dosing with the liquid ivermectin, you usually end up giving many times the dose of ivermectin that is found in Heartgard. I've heard a commonly recommended dose of 0.1 ml/10 lbs, and with this dosage, the dog is getting about 20-30 times the amount of ivermectin in a dose of Heartgard. ETA - I just googled and came up with two hits on Ivermectin being bad for greyhounds. One was the Comfortis website (imagine that) and the other was a chicken forum. Just curious, can you provide the link for the Comfortis site that said ivermectin was bad for greyhounds.

kudzu Posted July 25, 2012 Share Posted July 25, 2012 Weren't there some warnings about increased risk of adverse reaction when combining Comfortis & off-label use of ivermectin, such as using cattle Ivomec for heartworm prevention? Don't think this applied to Comfortis & Heartguard combined. Could that be the source of info on the site Pam saw? Also, I don't want to sound mean but in this discussion it doesn't really help to say you've heard warnings about Greyhounds & Heartguard if you cannot cite the source with an explanation of the risk. jjing gave a good example of someone misinterpreting data & applying it to sighthounds in general. I have heard someone say Greys ivermectin is more risky with Greys but claimed it was because Greys are more sensitive in general, evidence being their greater sensitivity to some anesthesia. That is simply not appropriate reasoning & in this case has led to person to an inaccurate conclusion. Quote Link to comment Share on other sites More sharing options...

greymatters Posted July 25, 2012 Share Posted July 25, 2012 JJNg, thanks for your very informative post! From my reading of the PNAS paper you linked to, I'd agree it seems highly likely that the mdr1 mutation was introduced into long-haired whippets via the sheltie. It's quite clear from the paper that this is a recent mutation in sighthounds, vs. an ancient one in the herding breeds.

Yes, absolutely - I almost put 'sighthound' in quotes for that very reason. And in the case of the silken windhund, the mutant allele almost certainly came from the long-haired whippet. Basically my take on the paper is that there is no evidence that this particular mdr1 mutation arose independently in sighthounds per se, nor that it is present in other sighthound breeds. Sorry for the thread-jack but I really appreciated JJNg's thoughtful commentary . To get back on point, sorry, no help re Sentinal/Program - we use Heartgard Plus here!
