Dog: Ferguson (Brown Male, born 02 Feb 2017)
Update February 2018: “Our very beloved Ferguson at the grand old age of 1yr and equally beloved Boo who is just over 3yrs now.
He is very much the dog we had in mind when you chose him for us. Thank you! As you can see he’s had a busy year growing. We weighed him last a month ago and was a healthy 58kg – I’m sure he’s 64kgs by now. Is it likely he will grow much more? We are still bringing his food up from SA and will continue to do so for as long as he is growing.”

Dog: BruceBoy (Red Male, 12 Months old in last pic below)

Update June 2017: “I still can’t believe how big Bruce is. My other purebred bullmastiff male that is already grown is so small compared to him. He must be 70kg already. We kept him on Royal Canin as you suggested. When he stands up he can look into our kitchen window and he sets off the beams when he does that.That black cape he had on his back is completely gone. He is the most loving and loyal dog to us.”

We love him despite him being naughty sometimes / Hy is baie mooi. Ons glo Duke gaan ‘n groot meneer word. Hy is vreeslik op en wakker en nogsteeds wil hy net die hele tyd by en om ons wees. Hy het `n verskriklike stem wanneer hy blaf. Nogmaals dankie vir jul. Ons is baie lief vir hom al is hy soms bietjie stout”

IMG-20151215-WA0010Update August 2016: “This dog is in a class of her own! She gets bossy with the little Jack Russell that’s constantly hanging onto her, but he constantly challenges her. We love her to bits and she gets a lot of attention. She is highly intelligent – we’ve, for instance, trained her to stay behind an invisible border line and she is very obedient to the command. I am so glad that we bought her from you. Please remember that you are always welcome to visit us. Thanks!”

Dog: Keevah (Fawn Female, born May 2014), Kzn, RSA.

“Hi. We are the proud owners of a beautiful girl furbaby. She is absolutely amazing with _iconsuch a gentle nature. She loves playing with my 5 year and 7 year old sons. She has never shown any aggression towards our children or other dog. She is extremely protective of the family. The reason for having her was and is as a companion. She has amazed us with how she guards the property which is an extra bonus.

She has been taken to the vet for regular vaccinations and the vet is thrilled with her – no elbow or hip dysplasia. I would like to thank the breeder, both Johan and his wife for the friendly welcome and advice we received and for breeding the most wonderful litters.

I will definitely be adding another furbaby pup in the near future and will only be contacting Johan again. Thank you so much for our wonderful girl. We love her so much and can’t imagine our lives without her. Best baby ever!!! – The Brider Family

Dog: Tyson (Fawn Male, born May 2014)

“I must say, we are extremely happy with our beautiful male that you bred. He has brought us nothing but happiness and is mRuzLogoy 19 month old daughters’ best friend.

He is growing so big and handsome, yet still a baby at heart and will steal any chance he can to sit on your lap for a cuddle. My daughter can go sit in his kennel with him and have his ears pulled, tailed stood on and her examine his whole mouth without me having to worry about her at all.

There is no aggression with food and us at all. He is very protective of us and will follow my daughter all over the garden. When he is tired of playing with her, he will just sleep next to her and guard her. Best dog and baby sitter we have ever had and boy is he a stunner. It is all about professionalism with this breeder whom is always willing to help. Thank you so much Johan” – Ruzaan and Family

Sargethrust Diba the great“Diesel is the best dog I have ever had. He’s getting big now (10 months old), but his temperament is still the same. He is the most lovable dog and like a baby lion the way he walks. We changed his name to Diesel from Juice because of his dark face” – Eddie and Family
