Hey there, I'm Arthur! I'm a 3-year-old male Mastiff. I am current on my vaccines, heartworm tested, neutered, and microchipped. 3 words that describe me: Energetic, Playful, Friendly Things staff and volunteers have to say about me: I'm a big goofy guy who loves to play! I love getting affection and running around outside. I like to pounce on my toys like a cat. I love meeting new dogs and playing with them! Activity level/Energy Level: (1-10): 7 or 8/10 Housetraining Status: I am working on it, a consistent schedule and lots of praise will help me learn! I should do well in a home: I should do well with children of all ages given proper supervision. I should do well with other dogs given proper introductions and time to adjust. My friends at CRHS are unsure how I'd do with cats. My favorite activities are: I love playing with tennis balls, other dogs, and getting affection from my humans! Things I need work on are: Leash walking and housetraining Any special needs: N/A Doggy day out notes: N/A Daycare Status: N/A My adoption fee is: $300 Training Requirement if applicable: N/A *If you are interested in adopting, please start by filling out an application available on our website and email it to us. https://www.couleehumane.com/adopt-an-animal

Story
Diesel is a sweet, sensitive boy who can be a little nervous around strangers, especially when they first come into his home. The good news is that he warms up very quickly and shows his affectionate, loyal side once he feels comfortable.Diesel has done well with cats and with some other dogs, though he can be selective and seems to do best with dogs smaller than him. Because of his shy nature, we recommend a home with all adults or teens, where he can feel secure and continue building confidence.With patience, love, and understanding, Diesel will make a wonderful and devoted companion.

Story
Handsome-boy Tonka needs a miracle. Due to a drastic change in his owner’s life, Tonka finds himself immediately in-need of a new foster and/or forever home. We know this is a big ask…as this BIG boy has quite a few specific requirements…but we are hopeful that his gorgeously giant smush-face will capture someone’s heart *just* enough to prompt them to give him a shot/bring him home!  Tonka’s details: 6 years old Is a mastiff/bloodhound mix Dog-friendly (Tonka LOVES other dogs! He actually tends to warm up more quickly to humans if there are other dogs around, and would prefer another dog in the home to romp around and explore with. He has done wonderfully with every single dog he’s met! ).  Does ok with dog-savvy cats. If the kitties don’t run, he does just fine…however if they do run, he will chase/terrorize them! Rides very well in a vehicle!  Is extremely loyal, loving, mellow, and snuggly. Fully potty-trained Loves to lounge, is incredibly smart, and doesn’t chew on anything he shouldn’t.  Tonka’s home requirements: Tonka’s #1 setback is that he has “stranger danger.” He is NOT a dog who’s able to be immediately approached by new humans. Therefore any introductions with him need to be slow and proper (no staring, no sudden behaviors/quick movements, no reaching hands toward him, no pets until he’s ready…& REALLY good treats!), with a calm, understanding, and patient demeanor. It can take anywhere from 30mins to several days for Tonka to fully adjust to new people…but once he does, you are “in” with him and he is SO faithful and SO loving! His person will need to be his advocate, as any/all encounters he makes should strictly follow the above guidelines. NO kids! He has a protective nature, and children come with more commotion + more noise. Therefore a kiddo-free environment is a must.  Much prefers females over males. Tonka’s past – before rescue – could’ve definitely held some misuse by a male figure in his life. He undoubtedly gravitates toward women, so would thrive with a single, confident female. Otherwise a couple [with a very patient male] could also prove to be the perfect placement! Toys and treats (especially if they include peanut butter! ) aplenty are a MUST! If living in town, a fenced-in, private yard is a necessity. He will react to/bark at (& has quite the BIG bark!) people walking by…and so quiet, country-living would be most ideal. More than anything, Tonka yearns for LOVE! If you show him compassion and earn his trust, he is amazing beyond measure! If you’re willing to give him that chance, he promises to return that love for the rest of his days.  APPLY HERE: https://newleashdogrescue.com Tonka is an eligible foster-to-adopt candidate, so please private message us with any interest/additional questions ##1983835##
