As several people on here have mentioned in the comments some border collies are sensitive to this product. From what I have read in the past, ALL breeds of collies may have a gene that makes them sensitive to Ivermectin, a common heartworm preventative. Other herding breeds such as the GSD are also reported to have this gene. However in GSDs it is much lower, only about 10% of them have it. If you are concerned I would recommend talking to your vet, there are also tests they could take to see if your dog carries this gene. However after reading about this product it says it uses imidacloprid and moxidectin as the active ingredients. I do not know the effects of these ingredients on herding breeds.
Refusing to stand for the national anthem angers many and sows division in our country. Kaepernick and others who have refused to stand for the national anthem have caused division among their teams, their fans, and across the country. The Santa Clara police union hinted they would boycott providing security at games after Kaepernick revealed his reasons for protesting the national anthem and wore socks depicting pigs in police uniforms. [ 14 ] [ 15 ] Fans have been burning Kaepernick's jersey to show their distaste for his actions. One video of a jersey on fire posted on Facebook was captioned, "He says he's oppressed making $126 million. Well, Colin, here's my salute to you." [ 17 ]
