I was buying Nexguard at Dr. de la Cruz, but with 4 dogs - 3 of them big ones - it was costing me around 6,000 every month. Personally, I am still fighting scabies, though it is better than before and actually, when I was in the US for three weeks, I was cured. No sooner got off the airplane and the itching began again.
Anyway, I am now making war with these parasites, treating the dogs as well - even though my friend Google says that scabies cannot live on dogs. Yesterday, I stopped at an AgroVet in the campo and we had a talk. He sold me the Nexguard for 3,000, not the 6,000 ish. And then he drove to my house and injected all four dogs with ivermectin at no additional cost.
While the AgroVets have more experience with large animals and cannot do all the delicate stuff on small pets, they do know their stuff about flees, ticks, and parasites and their charges are more reasonable.
Don't get me wrong, Dr. de la Cruz is a good doctor. All my dogs have been to him and I have no complaint about his doctoring. But for the bugs and parasites, the AgroVets can do the same treatments and charge less.
