You can get it at the feed store. Not sure how to dose dogs with it though.

I would steer clear of both Quest and Zimectrin for use in anything other than a horse. Quest has been the cause of numerous deaths in young horses since it hit the market. The problem with paste wormers is for small animals you can not get an exact dose, and thus are risking overdosing and killing your dog. You will think twice about cost if you have a dead dog on your hands.

The cow Ivomec can be bought at your local feed store. If your vet will not work with you find another vet. The dosage is pretty simple, but you still need to make sure you test the dog BEFORE you start it each year just as you would with the pills. I know how and used to use the ivomec, but since have gone back to the pills just out of lazyness. I might not be so lazy if I had more dogs. I am not going to go into doseages here as I am not a vet and I don't think that type of information belongs here. Ultimately overdosage can cost you your dogs life and it (cow ivomec) is not suitable for use on all breeds of dogs.

If your vet won't help you ask the GSD breeder to recommend a vet that will. If you explain to your vet that you truely can not afford to do the heartguard he/she may change his tune about helping you with the information.

I would recommend the Ivomec sheep drench(0.8 mg ivermectin per ml) vice the cattle injectable(1 percent) form. Much easier to oral dose them and the amount is still very small for heartworm prevention. You can use it for mange too if you are ever so unfortunate as to need it for that. A one litre jug (smallest format I've seen it in) will still put you back a bit of coin and will go time-expired before you can use it up.
Buying a jug of it and splitting it between a few other people might be a better option.

I use the .27% injectable (orally), but it is something that should be looked into carefully. Many breeds can not tolerate ivermectin very well. Collies, Manchester Terriers, Skye Terriers, etc.
