Story
India Rottweiler/Boxer/Dogo Argentino mix (short coat) Large Adult Female   This gorgeous brindle gal is India a 4 year old, 100 pound mixed breed dog who will be up to date on her veterinary care and spayed prior to adoption.  Her current family is not able to provide her with the time or care she deserves.   India is housetrained and crate trained, although, a crate has not been used in the past year or so.  She is used to living in an apartment and is said to be quiet and comfortable being left alone while her family works full-time hours.  She may whine initially when left in a new environment.  She enjoys daily walks for exercise and to do her business.   India is a Mastiff mix, and as such, will most likely become very attached to her family members but may initially be a bit wary of new people and animals.  She warms up to women more quickly than men.  India is currently living with 2 toddlers and is good with them.   India has very limited experience with other dogs and has not lived with another dog.  She has a Husky friend she likes to interact with on leash.  She may react to other dogs when on leash walks who are as far away as on the other side of the street and needs a strong and confident owner to help her work through this behaviour using positive reinforcement based methods.  She has also never lived with a cat.   Her family is able to bathe and brush her and she has been professionally groomed.  Her regular groomer says she is good for grooms.  At the veterinarian, she is muzzled for invasive handling.  Muzzles can be a great tool to help dog handlers feel safe.   If you are looking for a loyal, large breed dog to snuggle with on the couch and believe you can provide India with the care she deserves, please fill out the Adoption Application on our website.       Due to time constraints, we cannot respond to every email asking for more information on a dog. Please carefully review the bio for the dog and our adoption process https://www.speakingofdogs.com/adoption/adoption-process/.  If you are still interested in adopting, please fill out the adoption application form at the bottom of that page.

Story
Kodiak is the true definition of an adventure buddy! Do you enjoy hiking, running, biking, swimming or exploring? Kodiak is the perfect dog for you! In fact he is already and waiting at the door for you! He is an intelligent dog who is capable of learning extremely quickly. He already knows the commands sit, down, stay, come, and speak! Kodiak’s greatest strength is his loyalty; Up or down, good or bad, happy or sad it will be Kodiak and you against the world. What makes Kodiak special is that he has so much love to give. The exact reasons you are looking for a dog are the same reason Kodiak desperately wants his forever human. He will need a very active adult-only family to drain his energy in order to keep him happy. Kodiak is looking for an experienced and confident owner to continue working on his reactivity to dogs and new people. He will need a strong leader to slowly introduce him to new people using the methods he has been taught while at Dog Tales. Kodiak is not friendly with strangers, children or other animals. Therefore he will need to live in a house with a fully fenced backyard. Once he is comfortable with a person he will become very attached and a great listener. Kodiak is looking for his chance with someone special. Upon adoption, Dog Tales can provide training for Kodiak and you in order to set you up for success.
