Story
Ranger is the tallest of the males in his litter of 10. He is vocal and loves to tell you about his day and then tell you again! He loves to be pet and looks at a gate as a challenge, not a barrier. He is a typical busy puppy, who loves to play, run, and wrestle. He will be a large dog, as both mom and dad are over 75 pounds. He is looking for a forever home that has some experience with the food motivated lab and stubborn mastiff. It is recommended that he attend a puppy socialization class to become comfortable with friends who are not his siblings. He will be visiting the vet this week for his vaccines, flea and tick treatment, microchip, and wellness screening. He will come with a voucher for his neuter at 6 months of age at our vet in Woodstock. His adoption fee is $500. You must be 21 years old to adopt and provide vet and personal references. An application to adopt him can be found on our website www.oxfordcountyanimalrescue.com. Click on Adopt, then Dogs for Adoption and scroll to the bottom of the page. All applications are reviewed, and if we feel you might be a good fit for him, you will be contacted to arrange a home visit as well as for permission to speak with your vet. Repeated phone calls and emails with not advance your application. We are a volunteer, foster based rescue and there is no opportunity to meet him before an application has been approved. We thankyou for respecting these guidelines.

Story
MORE PHOTOS/VIDEOS: https://www.facebook.com/TLCRR https://www.instagram.com/taffyslegacycaninerescue https://www.taffyslegacy.com/koopa Koopa is currently being fostered in a detached home with 2 canine foster siblings. Koopa is house and crate trained. Koopa is a BIG BOY, and often doesn't quite understand that he is stronger than others, but he is doing very well with his training and loves to please his people. Koopa is very happy go lucky and playful with his canine friends, however he can make poor choices when adrenalized and does best with calm proper introductions. Koopa has had an incident with one other dog who was jumping up where he overcorrected, resulting in that dog needing stitches. With his friends, Koopa is fun and playful, and does well with supervised play with other well-balanced dogs. He doesn't always understand his size, and does play rough, so he would be best suited playing with other large breed confident dogs, as he can intimate more nervous or reserved dogs with his big size and big play style. He has shown some prey drive for smaller dogs, and would do best sticking to his bigger companions. We have not cat tested, but at this time with his size and prey drive we are looking for a home without cats. Koopa is a big loveable goofball and loves all people. He does well meeting new people and is a patio favourite hanging out with his foster mom and her girlfriends in public social settings. He has had one incident of grabbing a staff members coat and playing tug of war which caused it to rip - due to this he is looking for a home without kids or with older kids. Koopa is very food motivated and loves training, and has been going to a group training class weekly since his intake. He is doing very well, knows his markers, and continues to work on training daily with the kennel staff! Koopa is playful at the kennel, however he is a lower energy boy and has some hip/elbow issues that prevent him from participating in longer walks. He is looking for a lower energy home that can continue conditioning calmness and give him lots of puzzle toys and satisfy his mental energy. He is currently taking a glucosamine supplement. His perfect home would have power breed experience. Fun facts about Koopa: -This big guy is happy to be with and please his person! He loves to chew on wood and play in the sprinkler. He is hesitant to get into the bath tub but once he is in there, he is happy to get the attention and be scrubbed with soap and water! Koopa loves going for car rides but I have recently noticed that jumping into the back of the Jeep has been a struggle some days. I tend to get him to get his front paws up and lift his back end to help out. -Koopa likes to take shoes out of the closet and bring them to me but will never chew on or destroy. Likes to play with circle shaped foods before he eats. Needs work: Koopa is a big puppy in a full adult sized body! He can be easily overstimulated and always wants to be part of the fun! He would benefit from conditioning calmness and place exercises, as well as working on his crate training and leash skills. High prey drive in adrenalized situations. Koopa's foster mom works hard to manage his environment, facilitate proper introductions with trusted dogs and supervise play with his canine friends. Koopa is also working on puppy nipping - and uses marker language to get the point across that the behavior is unacceptable. Here is what Koopa's foster mom has to say about him: "Koopa is an absolute joy to have around. His goofy, owner pleasing personality makes him great to train and build an outstanding relationship with. He loves to be around people in new and familiar environments and receive all the attention. This big guy doesn't require a lot of exercise to tire him out and is very well at settling down in his crate or on his dog bed for some rest and relaxation. He loves to chew on his wood log or indulge in his licky mat when his Foster Mom makes him one. If I had more room and didn't already have two dogs, Koopa would be my first #fosterfail. He is truly a big treat!" ADOPTION PROCESS: taffyslegacy.com/adoption-process

Hello! My name is Jake!I came into the Guelph Humane Society in June very scared and under-socialized. My GHS friends and foster parents have been working very hard to help me learn that the world isn`t so scary. Once I warm up, you will see I have the best wiggle-bum. And I enjoy neck scratches and bum scratches. I`m still working on my confidence as little things can scare me, such as noises and movements. When I feel comfortable though, I can be quite silly and playful. I`m looking for an experienced home that is patient and can dedicate time to helping me continue to come out of my shell!MY IDEAL HOME INVOLVES…CHILDREN: No, I`m looking for an adult-only home.OTHER DOGS: No, unfortunately I don`t have much experience with dogs and aren`t very comfortable with them.CATS: Potentially, with cat confident around dogs.FIRST-TIME DOG OWNERS: No, I am looking for a family that has lots of dog experience.FENCED-IN YARD: Required.HOUSING ENVIRONMENT: No apartment buildings due to my fearful nature.SOMEONE HOME MOST OF THE DAY: Not necessarily.SOME OTHER THINGS TO KNOW ABOUT ME…ACTIVITY LEVEL: Medium.HOUSE-TRAINED: Yes!If you think I could be a good match for your home, click the `adopt me` button to apply!
