This handsome fella here is Pete (affectionately known to his foster family as 'Riggs').

Riggs is very well house trained. He does fine in a crate but will require a large one as he needs room to stretch out his legs. He often times naps on his back in his crate with his legs straight up in the air! He is wonderful with other dogs, both big and small, and knows how to play appropriately based on size. He grew up around young children and I don't foresee any problems in that regard. He does great in the car- just lays down and chills while enjoying the ride. He has an incredibly easygoing, affable personality and will get vocal when he wants or needs something. Riggs loves to just be BY you. He enjoys short walks, hanging out with you on the couch, TREATS, laying by the bathroom door when you take showers, meeting new people, going to watch kid's sporting events, and sleeping at the end of the bed at night to keep your feet warm.

Whoever adds this boy to their family is going to be extremely lucky. We love Riggs very much and it has been an absolute joy to have him with us and watch his progress :)

Riggs is a special medical Happy Tails case. He was originally adopted as a puppy from the rescue in April of 2015. When he was about a year old, Riggs started exhibiting stiffness and lameness in his back legs. His owners brought him to the vet and it was discovered that he had 'luxating patella'. This basically means his knee caps would slide out of place casing extreme pain whenever the knees bent. The condition most often stems from a congenital defect. More extreme cases require surgical intervention. Riggs fell into this category and his owners made the difficult decision to surrender him back to Happy Tails as they were not financially able to provide the medical care needed to help him.

Our family started fostering Riggs late October 2016. When he came to us he walked very stiffly, always trying to keep his back legs as straight as possible. You could tell he was hurting.

Once Riggs settled into our home, an orthopedic specialist was found. Surgery was performed on the left hind leg December 1, 2016. Recovery time was expected to be about eight long weeks where he had to have very restricted movement.

While healing, Riggs turned 2 years old on February 1, 2017! He thoroughly enjoyed celebrating with his furry foster brother and sisters! Frosty Paws Ice cream and frozen peanut butter Kongs were both on the menu!! :)

Soon after, Riggs was finally strong enough where he could put full weight on the left leg. On February 21st, we proceeded with the second surgery for the right hind leg. When the surgeon opened him up and got in there they discovered that this leg also had a torn ACL. This was repaired along with the patella.

Near the end of his second, eight-week recovery period, Riggs was still very sensitive and hesitant to put weight on his right leg. When the surgeon reviewed the new X-rays, a fair amount of arthritis was noted and it was determined that the implant used for repair was causing significant pain and inflammation. Riggs would need to have yet another surgery:(

Riggs is expected to undergo the implant removal procedure in mid-late May 2017. We will then find out whether a different type of implant is required to be placed or if the scar tissue alone will adequately hold everything together. So, as they say, the saga continues!

Through all the pain and recovery so far, Riggs has been an absolute trooper- always in the best of spirits! He is determined to play and be just like the other dogs. He can tear around pretty darn quick right now, even on 3 legs! He is very strong and gets super excited when the leash comes out as he knows we are going for a little jaunt around the block. Though he will never be a marathon runner, he is sure to be an awesome all-around companion!

Riggs is open for meet and greets! If this sweet, special boy has captured your heart and you are willing and able to provide the love and care he deserves, please fill out a pre-adoption application. Riggs/Pete's webpage can be found here:
