Story

3/20/25 We can only repeat what we wrote in August. Please consider giving Toby a home. He asks for little - just a soft bed in an ex pen where he can call that area his own. He likes to be on a schedule of eating/going out in the yard to potty. He needs a fenced yard as he has had no leash training. 8/6/24 Is there not a Chihuahua person out there looking for a little guy who does not ask for much attention? He enjoys being in his ex pen watching the other dogs but not being bothered by them. He's quick to get his business done outside but does need to wear a belly band inside as he likes to sometimes sneak a marking in. Where is his person? He's still waiting .10/24/23 Yes, Toby is a Grumpy old man. But he doesn't require much attention. He's quiet in his exercise pen and likes to stroll around the fenced yard. He'll find a sunny spot to soak up some sun, and then he's ready to come back in and climb back in his bed. Toby is a Chihuahua/Rat Terrier mix, approximately 6 years old. He came to us from being saved off the streets of a big Texas town. Toby needs a home that can help him trust people. He doesn't really want to be handled but likes to observe from a safe space out of the reach of people. Toby craves the safety of his crate - he will go outside into the fenced yard when you open his crate door, and he comes back in when called and will hop in his crate. He does not appreciate hands in his crate, so if you need to pick him up, talking quietly to him in an area where he cannot hide, he will allow you to pick him up and accept a few skritches. He's black and white and weighs about 10 pounds. He gets along with all the other dogs here and will need a securely fenced yard and someone who will allow him to relax and be with you without needing much attention until he knows he's safe. To inquire, please complete our application first, www.bongosbuddiesrescue.com . 10/14/25 Toby has been diagnosed with EPI, which means his body is not absorbing nutrients correctly. We have him on a supplement and 2 meds that are added to his 2 meals a day, and he has gained the weight he lost and is eating well. He does need to wear a belly band and his person to remember he can have no treats besides his 2 meals as he gets diarrhea if given food not treated by his meds first.

Story

🚨🚨ATTENTION RETIRES 🚨🚨 Lucille here, looking for someone retired she can spend her days with. She loves a nice lap, soft beds, bye bye rides, and a stoll around the neighborhood. Lucille is just 19lbs of bubbly personality. She is 7 yrs old and said to be a Chihuahua/Beagle mix. Her energy level is medium, and she doesn't require crating, if you need to run an errand without her. Lucille doesn't care for little kiddos or larger dogs, cats are probably a no go! She would be just fine, being the center of attention and doesn't need a large yard to satisfy her. She just had a dental and that little tooth that sticks out, not only adds to her cuteness, it doesn't stop her from treats. She is housebroken and will head to the door, letting you know, it's time. https://airtable.com/shrSbfFkCdeRMtZw2?fbclid=IwAR2Q_R2qh2bk6pwcDPnrL8722wGTJORafSAWJObVLvz0g6ASJOFxLIdvsRw

Story

I’m a gentle, sweet dog with a tender heart who’s still learning that the world can be a safe place. New things can make me a little nervous at first, but once I feel secure, my true personality shines—soft eyes, quiet tail wags, and so much love to give. I do best with patience, kindness, and a home with another dog. I thrive when there's another dog to play with. When I trust you, I’m incredibly loyal and affectionate, and there’s nothing I want more than a forever family who will help me blossom.February 5, 2026, 10:53 am
