Story
This playful girl is the perfect mix of affection and independence! Birdie adores belly rubs, cuddles, and of course, treats! She is very treat motivated which makes training fun and rewarding. She is housebroken and enjoys spending time with her people but she is also independent enough to relax on her own. Birdie knows how to sit and is learning other commands. She is currently working on her leash manners, and still has other basics to refine, but she learns fast and actually enjoys training. Birdie does have a prey drive, so a home without cats or small dogs is going to be the safest fit. And lets be honest — Boerboels are not your casual 'first dog' breed. They are powerful protection dogs by nature and you need to understand what comes with owning a dog like her. The good news? They are phenomenal family companions when they have structure and Birdie has been nothing but gentle and sweet with her entire foster family.If you are experienced with large working breeds and want a smart, loyal, fun dog to add to your family, Birdie is your girl. A local trainer, who is actually her foster parent, is offering free training lessons to whoever adopts her, because we all want to set her and her new family up for success from day one. Birdie is one year old and weighs 112 pounds.The adoption fee for adult dogs, seven months and older, is $250. All pets are microchipped, up to date on vaccines, and will be altered prior to adoption. If you are interested in meeting a dog, please stop by the shelter during open hours. Dogs may be in a foster home, therefore scheduling an appointment is recommended. If you have an existing dog at home, we recommend bringing it along to meet your possible new family member.helpingstrays.org

Story
Moose is the best name possible for this big boy considering he's as big as one! Talk about a GENTLE GIANT! He is your typical mastiff that is cool, calm and collected in any scenario. He NEVER makes a peep and just goes with the flow with everything you throw at him. He walked some of the parade and that was probably a week's worth of exercise to this lazy butt LOL! He loves going outside for about 10 mins then he's ready to come right back in, find a good spot on the floor and take a good, long nap. He is so patient and kind and would be phenomenal in a house with kids of any age. They can lay all over him or roll around the floor with him and it's not going to bother him in the slightest. As long as he's getting pet, he's one happy camper! He does awesome on a leash and even for his big size, a child could easily walk him since he stays in a heel position and never once pulls! He NEVER potties in his kennel so he is more than likely very house trained! He does fantastic with most dogs as long as they are as chill as him. He doesn't care much for dogs that are hyper and after him to play all the time since he's more of a couch potato! His adoption fee is $275 and this will include his DAPPV booster, deworming, current flea/tick, neuter, 1 year Rabies vaccine, heartworm test and a microchip. Please call 618-833-4915 to come meet him! Thank you! Are you interested in adopting this pet? Please click here: https://form.jotform.com/210158338747157 and fill out an application. Email us at: animalcontrol@unioncountyil.gov and make an appointment for a meet and greet! Address: Union County Animal Control, 385 Kaolin Road, Cobden IL 62920.

Story
Meet Duke! A two year old Mastiff mix that is looking for his forever family. In the home he is house broken, crate trained, and loves to be with his humans. As an XL breed dog, he could still use some reinforcement of basic manners. He's very strong on leash and tends to jump and get a little mouthy when he plays or gets excited. A family with large breed experience that is willing to invest some time and energy into basic training would be ideal. Another requirement would be no children under 10. Outside the home, Duke is a tad insecure and can be slightly reactive to new dogs. After a quick introduction, however, he does great (especially with female dogs). He can, however, tend to get too excited and possessive over toys so a family that can maintain boundaries in their home would be required. As for cats... this big boy LOVES them and would have no problem sharing his space with a dog savvy feline. If you are interested in Duke please fill out an adoption application at: https://www.dogsaredeservingrescue.com/adoptable-dogs/adoption-application/November 12, 2025, 1:26 pm
