Story
Duke is a lovable, giant of a dog. He is a large breed, possibly a Mastiff, and is estimated to be about 3 years old. Duke’s foster mom loving calls him booger, but he actually doesn’t drool much ! He knows basic obedience and continues to learn new commands in his foster home. Duke walks well on a leash and LOVES to go for car rides. In his foster home Duke lives with another large dog and 4 cats, and he would enjoy being adopted into a home with another dog friend. However Duke will need closer supervision with playing with other dogs. He is still learning how to live with cats, and while he does not seem to wish them harm, sometimes he gets too exuberant! Duke is loveable, goofy, sweet and enjoys attention. He will lean into you for scratches and likes to sleep nearby for hours. He spends most of the day sleeping on a pile of blankets, looking outside, and wandering in the sun. Duke will need a home with a semi- experienced dog owner. He is a kind boy but can jump and gently mouth when excited. He loves to play and cuddle, and tries to be super gentle, but he is a big boy with giant feet. Duke loves to meet children when out for walks in the park. He has some separation anxiety and can be quite the escape artist, so he will need a 6-foot fenced yard when left alone outside or a secure crate for inside. Duke gets very excited at the chance to play with other dogs, to help with his energy he is trained to respond to a e-collar beep or buzz. His adoption fee of $300 includes a microchip, vaccinations, and neuter surgery.

Story
I'm a strong and active boy who thinks I'm a lap dog. I get excited when it's time to go on walks, but then once we're walking, I'm calm. I do get excited when I meet kids, but after I will calm down and I leave them alone, unless they keep playing with me. Little kids might be afraid of me because of my size and run away from me and I think that they want to play, so just watch them. I would do best in a home with older children. My best day would be to: Going for a car ride to a park to go for a walk and then come home and nap. Other tidbits about me: I do fine being left out to roam the house when no one is home, because all I do is lay on the couch. I like being introduced to other dogs slowly and properly, otherwise I get over-excited. If, when I first meet new people and they have sunglasses on, I can get scared. As I am a pretty big boy, I can be strong when I get excited, so you need to be ready if you have the leash. I am not really interested in toys, but there are times when I do get the urge. I do slobber, so make sure to keep towels around.

Please note this dog is NOT an official Underdog dog, and you will be connected with the person who has the dog. Please Contact (Current Owner of Dog):  Leslie, yttaza@gmail.com MEET  ZEUS #17!! Zeus is a big snuggly well-mannered boy. He is low to moderate in activity and loves toys, eating ice, and being by your side. He likes to be the only animal love of your life. He has a best friend dog now that he loves to play with inside only. Once outside, he gets anxious and can get very aggressive with the dog. He shows no other aggression or guarding inside. Continued training may help the issue. Leash training will be helpful too (he is reactive with some dos). Zeus eats with all the other animals and is very respectful, waiting his turn to get his bowl and for each dog to finish eating and drinking.    Zeus needs a fenced yard. He loves to ride in car. He jumps in and out and will lay down for the ride, with or without dog seatbelt. He is easy to put leash and harness on, he will sit for the process. He is crate trained and sleeps in his crate at night. He is fine out of it too.  Mostly, he wants to please you.   Zeus is a lover and really the best boy. He just does not do well with dogs outside (even his BFF).   He will come with his crate, bowls, leash, harness… He is up to date on vaccinations and annual examination. He loves baths, showers (and has his own robe), and most groomers. Also, good with cleaning with wipes, ear cleaning, and nails…teeth brushing is a fun activity (arm and ab day for you). He has never growled or grr'd at me while I do all of his hygiene. He loves his people.

Story
Penny came to us from the euthanasia list at the county shelter. She weighed a severely overweight 110 lbs and suffered from chronic eye issues. She was going to be euthanized for her medical needs. She was a volunteer favorite at the shelter, and what was more than clear to all of us was that this precious girl had simply never been given the chance to live the life she deserved. Since coming into our care, Penny has lost over 45 lbs and is looking better than we could have ever imagined. She has transformed into the type of dog who would fill her perfect home with all the love in the world. She loooves to play, adores her toys, has learned impressive obedience commands [and impulse control!], and she really is something special. Given her size and strength, Penny would do best with a person or family who can keep up her obedience work at home so she can continue to be her very best self and get in all the walks and activity that she needs. And speaking of home, she would love to be your one and only fur baby, and she made me promise to tell you that a yard for her would be a dream come true. Penny's adoption fee includes her completed veterinary exams, bloodwork, vaccines, microchip and spay. With her in it, we can promise your home won't feel empty again, and she is sure to steal your heart 100 times over...guaranteed! To meet Penny, apply here https://lovethemallrescue.org/penny. She is sure to steal your heart 100 times over.

Story
  Calling All Mastiff Lovers! Meet Zena, a stunning 3.5–4-year-old Neapolitan Mastiff with a heart as big as her paws! This gentle giant is sweet, loyal, and absolutely loves being around her people and calm doggie friends. Recently, Zena went on a small hike and did great—she enjoyed all the smells, never reacted to other dogs or people on bikes, and showed off her perfect leash manners. She leans into you for love and pets, knows sit and shake, takes treats gently, and rides like a pro in the car. Her favorite thing in the world? Belly rubs! Zena is currently living in a kennel at a boarding facility, but kennel life isn’t her thing, and she’s eager to find a foster or forever home where she can thrive. This hidden gem is spayed, up to date on vaccines, and ready to meet her new family. Let’s help Zena find her happy place and give her the loving home she deserves! Ready to meet Zena?

Story
Hi, my name is Noel and I was born on 8/17/24. I am a husky, chow, St. Bernard, and GSD mix, one of my siblings that was adopted did a DNA test! I am going to be a big girl so I would prefer a home with a yard, or an active family to take me on lots of walks, runs, and hikes. I am working on potty training and have not worked on leash training yet as I am not fully vaccinated. I will be spayed on 12/13 and get my rabies vaccine at that time, I am microchipped and have two more sets of vaccines. I would love to find a home to call my own, could it be with you?
