MDR1 gene and toxicity to heartgard med
My vet gave me a free sample of Heartgard plus for my Dutch Shepherd puppy and wants me to give her one ecvery month. I have read that herding breeds should not take the drug ivermectin which is in Heartgard. I mentioned this to my vet and she just said not to worry. Herding breeds have a possible multi drug resistant 1 gene (MDR1). Anyone here know any thing about this or have ever had any toxic reactions after giving Heartgard? I got my info at www.1800petmeds.com

I have heard of this in dogs like Shelties and Collies, never in shepherd types.

I give straight Ivermectin monthly to all of my kids, and all the the rescues that have come through. I have never heard of a dutch being reactive. You'll be fine.

- Tell us about yourself: I was introduced to the Dutch Shepherd breed during my time as an Army veterinary technician working with Military Working Dogs. I fell in love with the breed and by pure chance happened to meet a DS in a local rescue who was a police K9 washout and was up for adoption. We adopted Zodiac right away and she has been an important part of our family ever since. We currently compete in Rally-Obedience and participate in Agility.

When I was in vet tech training they told us that only applied to border collies, not the other herding breeds. All of our military working dogs (German, Belgian, and Dutch Shepherds) were on Heartgard monthly.

- Tell us about yourself: I am in New York State. Got my first DS about 14 years ago (more or less as a rescue- lost her in Nov.). After years of GSD's, and a few dogs of other breeds (Rotti/Beauceron/Ger. Shorthaired Pointer/ Yorkie and my current Jack Russell) I now have another DS, 4mo female, no name yet, tho I have a few in mind.
Also have a horse-old quarter horse mare-32.

Re: MDR1 gene and toxicity to heartgard med
I had an imported GSD male (Pitt), quite a long time ago, who was unable to take ANY form of heartworm meds. Back when Dirocide was used daily, and Ivermectin was pretty new. We never did figure it out, but this was when heartworm was first an issue in my area, and the Vets were no help at all. (Also before everyone had computers and information at your fingertips.) He was a grandson of Uran v Wildsteigerland, and as far as I was able to find out, the only one in the line with a problem. None of his pups had any problems either.
I also imported a Uran daughter (Cella), who had no problems. I ended up using Levasole on the male, with good results.
Generally it's considered to be pretty safe, except for the Collie breeds.
I use a .05% solution of Ivermectin with no problems, $25.00 for 60cc bottle (lasts forever), but I give it every 6 weeks instead of the veterinary recommendation of every 4. (That's a whole different topic for discussion.)

- Tell us about yourself: Dogs are my life, what can I say. GSDs primarily for nearly 50 years til bringing in my first DutchShep about 4 years ago. GSD rescue for 9 yrs, nearly 200 thru my home, rehabbed, adopted out. Been involved in AKC ob, herding, tracking, agility; Schutzhund-DVG; scent detection (HR-water)&narcotics, some patrol work. Mostly herding training at present on my little farm.
Re: MDR1 gene and toxicity to heartgard med
I've used Ivermectin on my crew, including 5 herding breeds, for 15 or so years. That includes a couple hundred GSD rescues too. Our old show circuit club included Shelties, Aussies and BorderCollies and those folks would never give their dogs Ivermectin. They called it the 'white paw' complex.
