Story

Maggie is 3-4 year old Terrier/Chihuahua/Poodle mix weighing about 15lbs. Maggie came to us over a year ago from a hoarding case where there were over 60 Chihuahua/Poodle mixes living in a small home in Denver. They were all incredibly under socialized and neglected, with most of the females being pregnant. We were able to take in 5 of the pregnant moms from Maxfund to help get them into a safe and comfortable place to give birth and raise their puppies. We also took about 8 other dogs from the hoarding case to start them socializing and learning how to "dog". Maggie is now the last dog from the hoarding case and needs her forever family. Maggie has clearly been through a lot and still has a long way to come. She is a sweet girl but still pretty timid around humans. She will come and snuggle with her foster Momma on her terms but it did take an incredibly long time for that to happen. Maggie really needs a human who can be patient with her and give her a forever home with lots of love knowing she came from an incredibly rough situation and will probaly never be a completely "normal" dog. Her fosters describe her as more of a cat-dog. We know she could make more progress with some training as well. We will require she goes to a home with another dog so she can continue to learn how to trust and be a dog.

Story

Pitch is a 3MO adorably scruffy Terrier mix weighing about 7lbs. We are guessing he will be about 15-25lbs when full grown. Pitch came from Texas, where he was dumped on the streets with his siblings. They were all terrified, and just trying to survive. Thanks to our wonderful rescue partners, she was able to get them all to safely until we could transport them here to CO. Pitch love to follow his foster momma around the house and play with his other four-legged foster siblings. He is curious, affectionate, and oh so sweet. Putzi seems to learn quick and is well socialized despite everything he's been through. He is such a great little pup and will make a wonderful addition to any family who has the time and love to give a forever new family member.

Story

Teddy is a 5MO, 7lb Terrier mix. He is the cutest little scruffy, scraggly, snuggly little guy. We are guessing Loki will be about 12-15lbs when full grown. We don't know their actual breeds, but they do NOT seem like they are going to be 100% nonshedding or hypoallergenic. They will most likely be lower-shedding though! Teddy and his brother were dumped at a shelter in Mexico. The shelter reached out to one of our rescue partners here in the states in hopes we could take them and find them wonderful homes here in CO. Teddy and his brother made their way to CO a little while ago and are healthy, happy, well socialized, and ready to find their forever families! Teddy and his brother are both playful, smart, confident and loving. They get along with other dogs, kids, and humans. They would each do well in a home with another dog to play with or someone who has time to train, socialize, and exercise a puppy. These two pups are on their way to be amazing pups! If you are interested in adopting Teddy OR Loki, please fill out our adoption application at brighterdaysdogrescue.com ##2657290##
