Certifect is a new product which is more effective against ticks than its predecessor Frontline.
I have seen a couple of postings elsewhere warning people to be careful about using the new flea and tick treatment certifect. Some animals are allergic. I saw a photo of a greyhound with a terrible rash, looked like he'd suffered burns. You can read another discussion here, from someone whose pet suffered a more serious reaction: http://www.horseforum.com/other-pets/careful-certifect-new-tick-flea-killer-122596/
Reading that story also reminds me that if you have a collie or collie cross, many collies have serious adverse reactions to
ivermectin and related chemicals, including milbemax wormer. Ivermectin sensitivity is mosty found in smooth and rough collies (the lassie type) but care is recommended with other types of collie so may also affect lurchers with collie in their bloodlines http://www.collienet.com/health%20topics/MILBEMAX.htm
