A huge thank you to Protection Dogs for trusting us with such an incredible protection dog. We couldn’t be happier. He’s everything we hoped for and more. Our whole family feels safe, proud, and absolutely in love!

I bought a Belgian Malinois from Kostas several years ago, and I can confidently say it was one of the best decisions I’ve ever made. From the very beginning, Kostas was there every step of the way—always available to answer my questions, offer guidance, and help me navigate life with my new dog. His deep knowledge, professionalism, and genuine passion for his dogs set him apart. It’s rare to find someone who truly cares about both their dogs and their customers the way Kostas does. Even years later, I know I can still reach out to him if I ever need advice. The quality and temperament of my Malinois exceeded all my expectations, and when the time comes to add another dog to my family, there’s no doubt in my mind—I’ll be going straight to Kostas. If you’re looking for an exceptional dog and an even better person to work with, look no further. I highly recommend Kostas to anyone searching for a loyal, well-bred companion

Protection Dogs GR and Kostas are very knowledgeable and experienced in both determining the potential of canines and training the canines that qualify for their protection dog program. Kostas is very discerning and openly shares the rationale behind his determinations. He is a pleasure to work with as he is very honest and patient. I had a copious amount of questions (like really - a LOT) and he answered them all. His dogs are raised and trained with his family, and you can see that this is truly his passion.

Honestly i didn't think a dog could be so smart i was used to only say fetch sit lay down give me your hand the basics . I bought her for my self but since then she has bonded with my niece and vice versa the duo now is inseparable , she wont eat from others or care for anyone when she is with my niece you tell her to stay there she wont budge .I honestly don't know what to say else i have had pit bull Rottweiler Pomeranian french bulldog boxer they were all lovely best companions but i have never seen a dog this disciplined . Thank you so so much , i definitely getting a male soon to make them a couple again thank you so much .
