Story

Molly's people moved and left her behind. Molly is a playful loving, sweet girl who gets along with everybody. She does not jump fences but she loves to get out and run. Sometimes she acts like a puppy even though she's 5 years old. She's a big girl and she uses her muscle sometimes to push her way through the other dogs and get where she wants to go but she never attacks anybody or does anybody any harm she just likes to throw her weight around lol. She is a doll would love someone to wrestle with and go on walks with. She is Crate trained and house trained but she would love something to chew on in her crate at all times. Like I said, she still thinks she is a puppy with her chewing! She's good with big dogs and little dogs! Molly has been with us for over a year and would very much like a home of her own. Please come and meet Molly today. She would love to be your couch potato partner.

Story

Hello. My name is Dutch. I am a 1 year old Mastiff/Lab mix male that weighs around 88 Lbs. I was recently surrendered due to my owner's health declining and them no longer being able to care for me. So now, I am hoping to find a new furever family. I am a silly boy who likes to play. I do walk well on a leash and get along with other dogs that can match my energy. I am a very strong and solid boy who is more on the dominant side and need friends who can keep up with my strength. If you have another dog at home, a meet and greet is best prior to adoption to ensure we get along. I do not do well with cats. I am a good and loyal boy who is a giant puppy in need of a little TLC, patience, and consistent training in my life. I have been searching for my furr ever home for 112 days as of 05/21/2025 and am now considered a Diamond Dog! My adoption fee is $75. I am neutered, microchipped, current on my rabies vaccination, boosters to date and heartworm negative! If you are interested in adopting me, please complete an online adoption application at https://rockwalladoptions.com/adoptfoster/adoption-application/ Once your application is submitted, RAC staff will be in touch with next steps. All animals, unless otherwise noted in their description, are at 1825 Airport Rd. in Rockwall, TX. Hours of operation are Monday-Friday 9 am to 6 pm and Saturdays 9 am to 5 pm. For questions, please call 972-771-7750 ext. 2 or email info@RockwallAdoptions.com. IMPORTANT NOTICE: All shelter animals are required by Texas state law to be spayed/neutered. RAC completes this procedure at the age of 12 weeks. If you are adopting a pet under the age of 12 weeks or an animal that has not yet been spayed or neutered, you will be required to return the pet to our facility on the agreed upon date set at the time of adoption. This policy is non-negotiable and violation of this health code is a criminal offense. May 21, 2025, 3:45 pm

Beignet (Becca)

Mastiff

Female, 2 yrs 3 mos

Mesquite, TX

Size

(when grown) Large 61-100 lbs (28-45 kg)

Details

Not good with kids, Not good with dogs, Not good with cats,

Story

Meet Beignet! She is a 2 yr old spayed female Mastiff mix that weighs 80lbs. She was surrendered to the Mesquite Animal Shelter on 1/30. She is an amazing girl! She doesn’t show well in her kennel as her anxiety of being there for long periods of time shows. Once you get her out of her kennel, her demeanor instantly changes. She walks calmly, stays by your side and doesn’t pull at all on a leash. She enjoys being petted, takes treats very gently and knows the sit command. Beignet is friendly, and enjoys investigating her surroundings. Having a secured backyard to play in, but live indoors where she can cuddle close with her human companions, and take naps on her dog bed would be ideal. As she is a big girl she would need to live in a home, not an apartment. Also, she does not do well with cats or small dogs, but is ok with larger dogs. If you have another dog in the home, please ask the shelter for a dog test. She is truly a very special girl and you just have to meet her, to look into her eyes, to see how much love she has to give. Come spend time with her and you will see how amazing she is.

Size

Details

Not good with kids, Good with dogs, Not good with cats, House-trained, Spayed or Neutered, Shots are up-to-date,

Story

Hanky Panky is one of those Saint Bernards that we will never forget for the rest of our lives. He has the temperament and look that every Saint should have. He is not a young boy, but he is not an old man. He has a beautiful short hair coat. We think he is approximately 5 years old. Hanky Panky loves attention, will walk right by your side, knows how to sit and is great with all dogs. He will make you smile every day. He weighs 135 pounds, and he is heartworm positive. St Cloud’s rescue has already neutered him, and he is on the slow kill method for the heartworms. This will take between 6 months to a year to complete. He is having some intestinal issues that may be due to his medication for the heartworm treatment. He is house trained. He does have a sensitive stomach and we are working to find the food that works best for him the best. He should weigh about 150 pounds when he is healthy and eating properly. He loves toys but he can’t have toys because he has a tendency to eat them. In concern for families with small children, we will not adopt a dog to a home with any child under the age of 5. This is due to the large size of Saint Bernards and the safety of your children. Our Saint Bernards are not aggressive or mean in any way, they can just knock down children easily. If you would like to visit our pups please contact St. Cloud's Rescue at www.stcloudsrescue.org or call 972-679-5319. The first step in adopting from St. Cloud's Rescue is to complete an application. The application may be found OUR WEBSITE at www.stcloudsrescue.org. Please click on the application process, complete and then email it. Once the application has been sent please call us to confirm that we have received it. St.Cloud's Rescue maintains the right to deny applications to anyone for any reason we see fit.

We require a home visit prior to all placements. All our dogs must be microchipped at a cost of $20.00. There is a $350.00 donation fee. All dogs adopted through St Clouds Rescue must be indoors.
