Story

Meet Rony At just 4 months old and a teeny 4 pounds, Rony is a pocket-sized burst of happiness! This tiny guy is a bundle of fun and energy, always ready to play, cuddle, or trot after you with his wiggly enthusiasm. He’s got that irresistible puppy curiosity, a heart full of love, and a face that makes you smile without even trying. Rony may be small, but his personality is huge—he’s the kind of pup who will turn everyday moments into adventures and nap time into the coziest part of your day. If you’re looking for a best friend who fits perfectly in your lap (and your heart), Rony is ready to meet you and start his forever story. Warning: adopting Rony may result in excessive smiles, happy chaos, and lifelong love. Rony is working on potty training and doing great, especially for such a young puppy; you just have to watch him very closely. He is really good in his crate and sleeps through the night entirely in the crate. Rony is being fostered in Denver, Colorado- available to meet! Red Fern Animal Rescue offers a two week foster to adopt trial in your home before finalizing the adoption to ensure the animal is the right fit for you, everyone in the home, human & animal, and vice versa.

Story

Lashes arrives in Colorado Saturday 2/7/2026 and needs a committed foster home or adopter to welcome her! Lashes was found as a stray running the streets in the Rio Grande Valley on the Texas/Mexico border. Unfortunately, nobody has the good sense to claim, or reclaim, this sweetie- their loss! You're in the unique position to claim her and give her a furever home! From foster: “She is very sweet, definitely a kisser, she stays in her crate with no issues when we have to leave, if loose in the house we just gotta keep an eye on her since she is a chewer, she doesn’t like when my big dog gets close to her crate and she is scared to play with her since she is too big, she waits until I take her out to potty so no accidents in her crate at all, she likes all people including my 8 years old. “She is not a barker she is a very quiet girl unless my big dog walks by her crate when I’m taking her out since I take them separately. Energy level? “I will say she is 5 out of 10, she still has energy to play and run but if I take her to bed with me it takes her maybe 5 minutes to stop kissing haha and then takes a nap next to me” Lashes is currently living in a foster home in San Antonio, Texas, awaiting an adopter or open foster home in Colorado to bring her up and into their home. ***Lashes is being posted on behalf of our partner rescue in Texas- the process and adoption will go through them. The adoption fee does not include the transport fee (usually $125-200/dog).*** Red Fern Animal Rescue is a 501(c)(3) non-profit foster-based animal rescue in Denver that saves animals from abandonment and neglect in South Texas for new lives in Colorado. We primarily rescue dogs off the streets and from kill shelters in San Antonio. ##2650731##
