I am a long-time lover of pitbulls! I finally have the perfect female puppy! Her name is Icys and she is a chocolate red-nose! She is from the Castillo bloodline! She is now 4mos old. I got her from a family in South Texas: bordertownpitbulls.com , which is also where her pedigree can be found online. We're finally just about getting over the housebreaking part and it was somewhat a struggle. I was wondering what people thought of the Castillo Bloodline? I also would like to know what the thoughts were as far as supplements? Are their any real supplements people feel are necessary, and why? I have been interested in finding her supplement for her coat, which it looks nice but she does have dry skin. I also put a deposit down on a male which has not been bred yet! He will be half Gladiator/Castillo. I found him with northlandpits.com . Do any of you know of northlandpits.com?
