Story
King Tutt / Male / 2 years / 66 lbs / Mastiff Mix / Good with Dogs / No Cats Please / Good with Children / From Tennessee / Fostered in Toronto ** Follow King Tutt’s journey on Instagram @tk_fetchfosters Meet King Tutt! This beautiful brindle boy came to us from Tennessee where he, his brother and dad were left without a home. Despite his difficult past, King Tutt is full of charm and is sure to win over everyone he meets. King Tutt’s foster’s describe him as loyal, loving and playful. He loves to make new friends, whether human or canine. Being with his people is important to him, whether it is out on an adventure, playing at home, or lounging on the couch. King Tutt can be a silly guy, who enjoys exploring, playing with toys, swimming, and running in the yard. He will make a great addition to an active family. King Tutt is a social butterfly, who loves to meet new people, and soak up attention from those he already knows. He has shown no hesitation, and will greet people with excitement, ready for scritches and cuddles. King Tutt has met older children and done well. He sees them as more humans to give him love and attention and will soak it all up. He can get excited and jump, so interactions should be monitored. Although he has not met young children, given his demeanor we think he would do well with respectful, dog-savvy children. King Tutt is very adaptable and is happy to be where his people are. Given this he would do well in any living environment, so long as he has access to greenspace. A home with a yard would be amazing, as he loves to run and play, but if given sufficient exercise he will be good. He really does love to explore and play outdoors, so an active family that shares his love of nature would be perfect. Playing with other dogs is one of King Tutt’s favourite activities. He currently lives with another dog and enjoys his company. King Tutt would do well solo as well, he would just need opportunities to socialize and play with other dogs. King Tutt has not met cats yet, so we are looking for a cat-free home at this time. King Tutt is a busy guy, who needs both physical and mental activities each day. He is gradually learning his leash manners, and enjoys the time outside to sniff. He has shown no signs of reactivity, or fear with other people/dogs, or city sounds. He can pull when he gets excited, so his new family should be prepared to continue working with him with his leash manners. At home King Tutt is learning his house manners with ease. He is house-trained, crate-trained and working on his commands. He has not been given free reign of the house if he is alone yet, as he is curious and may counter surf. King Tutt is not overly food motivated, but he loves to make his humans proud, so training is lots of fun! Prior to coming into care, King Tutt tested positive for Ehrlichia which is a tick-borne infection and is not contagious. A CBC was performed to see if there is an active infection. King Tutt 's CBC came back indicating that there is no active infection however it is recommended that Ehrlichia positive dogs get an annual blood test to monitor and that pre-op blood work including a CBC test and platelet count be performed before any surgeries or dental extractions. King Tutt also has mild enamel hypoplasia which is thinning of the enamel on his teeth. Homecare will help with brushing but he may require professional dental cleaning in the future. He should avoid hard chews, toys, and treats as his teeth will be more prone to breaking during play. If you’re interested in adopting King Tutt, please apply at https://www.fetchandreleash.ca/adoption-info#adoption-form King Tutt’s adoption fee is $850.

Name: Breed: Age: Gender: Weight: Good with cats or Small Animals: Good with dogs: Good with Young Children: Good with Older Children: Fenced Yard Required: Crate-Trained: House Trained: Name: Bagel Breed: Mastiff Cross Age:  Approx. 10 Months Old Gender: Male Weight: 63lbs Good with cats: Not Tested Good with dogs:  Yes Good with Children: Over 7 years old Fenced Yard Required: Preferred House Trained: Yes Location: London, Ontario   Meet Bagel: Your new BEST friend and the very BEST boy:   Bagel is a bundle of love just waiting to shower you with his affection. This sweetheart is a lover of both people and dogs, making him the perfect companion for a family, as an only pet or even someone with other pets in the home.   Bagel is so smart and eager to please and his amazing behaviour means you’ll have no handling issues—especially important now that it’s jacket-and-bootie weather! He’s a dream to walk on his front-clip harness.  He already knows commands like sit, leave it, and he’s quickly picking up mat, lay down, and come.   Bagel loves a good play session, but he’s equally content to snuggle up close to his humans for some downtime. His sweet nature and easy adaptability make him a fantastic fit for almost any home.   A home with more that one person would be best so he doesn't need to be alone very often. He will bark when left alone so a home with no shared walls is a must.   Bagel deserves a loving home environment to show him just how wonderful life can be. If you’re ready to welcome this amazing pup into your life, Bagel will repay you tenfold with loyalty, love, and endless tail wags.   Bagel’s adoption fee is $650 which includes his vaccines, preventatives, microchip and neuter.   If you think you can give him a happy ever after home, please complete our online adoption application at this link https://www.animalert.ca/apply/dog-adoption  If you wish to learn more about Animalert, please visit our website at Animalert.ca Due to the volume of emails, phone calls and messages Animalert receives, it is not possible to respond to all applications.

Story
File #24-295 Current Foster Location: Arnprior, ON *Please note that we do not typically adopt outside of a 2 hour radius from the foster dogs current location* Hi, Im Kitten. Yes, Kitten. Go ahead and laughits good for the soul. My name is ironic because Im basically the opposite of a cat. Im outgoing, bubbly, and, well, clingy. If you leave the room, Im coming too. If not? Cue the dramatic howls. My day starts with a leg stretch, some morning zoomies with my foster sister, and a hearty breakfast. Then, its lounge mode until our afternoon walk. Evenings are for more playtime, walks, and cuddles. Oh, and dont forget my enrichment games and lick matgotta keep this brain sharp! Im a playful guy who loves dogs, is curious about cats and is gentle with kidsthough I sometimes forget Im not a lap dog. Little humans might be too little for me. I take cues well from other dogs and am eager to please, but my manners could use a little polishing. Im also not the best at being alone, so an apartment or attached living isn't the ideal home for me. Now, heres the thing: Im still very unsure around men, so progress will take time, patience, and a kind, confident owner to help me overcome this. Slow introductions, lots of positive reinforcement, and understanding will be key to helping me feel safe and secure. One last thing! Smelly toots are part of the packageconsider it my love language.
