The ONLY place I will ever board my dogs. I have 2 big, highly active dogs. One has severe anxiety and requires, and Jess is the ONLY person my family has been able to find where he feels 100% at home. The castle is mine and my families go to for pet sitting. 10/10 stars, Jess is the only person who is able to makes our pets feel safe and cozy. THANK YOU, to the castle, us and our pups love it there!

I boarded my cat Goose at Knox’s K9 Castle and had such a great experience. It’s not easy trusting someone with your cat, but they made sure she was comfortable, safe, and well cared for. I got updates and could tell she was in good hands. I’ll definitely be bringing Goose back whenever I need boarding.

Jesseeka is the best! She always ensures that our dog is safe and well cared for. She has a passion for caring for her animals! She has a wonderful animal friendly home and many services to offer such as grooming while you’re away! I’ll always send my dogs here🩷

If you’re in the Merrillville area and need a place you can actually trust with your dogs, check out Knox's K9 Castle. I’m big on supporting good local businesses, and this is one of them. Jesse, the owner, runs a great operation. She’s hands-on, professional, and you can tell she genuinely cares about every dog that comes through the door. Titan and Sally are always excited when we pull up, and that says more than anything I could write. Dogs know. The place is clean, organized, and you can feel the positive energy as soon as you walk in. It’s good to see someone in the community doing things the right way and putting real effort into what they’ve built. Big shoutout to Jesse and Knox’s K9 Castle. Merrillville’s lucky to have them. Titan and Sally will definitely keep coming back. 🐾

Repeat visitor here! Jess is consistent with the attentive care she provides for my baby, Malakai! I received plenty of pictures and text notifying me how my fur baby was doing! I will be using her services for boarding as well, as I am confident my pup will be in good hands! If you are looking for a responsive, caring, and attentive provider for your fur baby, I urge you to give Jess a try! You won't be disappointed
