“We might be crazy… but we are SO in Love! THANK YOU Katie Deer Creek Mastiffs Welcome home Sweet Boy”
“I thought we might hold on to the big reveal until next week but who am I kidding? We're too excited for that. So please let me introduce you to the newest member of the Hopper family…. Gunnar. Gunnar is a 7 week old Mastiff puppy and will come home next Sunday to start his new life with us! We couldn't be more excited and thankful. [Update - June 30:] Baby G's first pig ear! (Fully supervised and in small amounts only). Sent with love by his PA mama, Miss Katie.”
“Great experience working with Katie to get our new girl. Wonderful puppy!”
“We are absolutely in love with this girl - Eleanor!!! She is everything we hoped for when we got her. Katie was the best at helping us pick the best addition to our family!! Thanks Deer Creek family”
“So pleasant and easy to work with, we had been looking for a breeder and we had one conversation with Deer Creek Mastiffs and we knew we had found someone who truly cares about their pups, we have the best pup so lucky to have our girl !”
“Great experience from start to finish and beyond getting our pup. She is very helpful when it comes to suggestions on food and care. We also got to meet the rest of the dogs on property for including the parents. Would highly recommend for anyone looking for one of these gentle giants.”
“We've had our new mastiff pup for approximately two weeks and she is one of the smartest dogs we have ever had, quickly picking up on her intro to obedience training & housetraining. She also has a great personality! [17 months later:] This is Deer Creek's Darlin Pippa, she's 17 months and the best girl. I can't say enough about the quality of these English Mastiffs!! Great breeder. Healthy lines. We just love her!! Thanks Katie!”
“Katie is an amazing breeder 💫❤️ she is really involved and dedicated to her puppies and dogs - she gave all the instructions to make everything easy and smooth - as we are living on a small island the travel was not easy but we find a solution and she trusted me - her dogs live in the family as when Gaia arrived at home, she was already confident with noise and people - thank you Katie for your amazing job and your true love for this wonderful breed - Gaia is a GEM 💎 💖🥰”
