Shamrock | Available

Meet Sham! | This handsome Border Collie mix is estimated to be around 2 years old and has already proven himself to be an incredibly sweet and friendly pup. From the moment he arrived, he’s been eager for attention and happy to make new friends. He does great with other dogs and seems to have a gentle, easygoing personality that makes him a joy to have around. He has a big prey drive, so cats, birds and other small animals are a no-go for this guy.

He came to us from a shelter in Oklahoma, where he unfortunately landed on the euthanasia list after testing positive for heart worms. Thankfully, his X-rays showed a perfectly healthy, normal-looking heart and lungs!

After many conversations with our vet and lots of our own research, we’ve decided not to pursue the traditional heartworm treatment. Since Shamrock is showing no signs of illness, and his overall health is excellent, we chose the route that is gentler on his body: monthly preventives. These will weaken the existing heartworms and prevent any new ones from developing. Heartworms naturally die off within about two years, and with consistent preventives, Shamrock will gradually clear them on his own.

Sham is working on all the important foundations for success. He is potty trained, finishing up his crate training, leash manners, and basic obedience. He is not perfect with all of these yet, but continued work from his adopters will ensure success.

His adopters will need to continue monthly heartworm preventatives to ensure continued heath and care.
