Glad to be a part of this forum. After 10 long years of wanting a presa canario I am finally the proud owner of a beautiful 10 week old brindle male presa canario puppy. I have to say I am a little disappointed not in the dog but in how over hyped these animals are, maybe I AM a little disappointed in the dog as I expected "more". As an experienced dog handler and trainer far from professional but I've had 2 sport trained rottweilers about 15 years ago so I know a few things about dogs. I purchased my presa from a well known reputable breeder so I believe I got a top quality dog but if this is top of the line this breed is definitely lacking. It seems like it is hit or miss as far as getting a "solid dog". One thing I noticed in my puppy is a lack of drive he will chase a rag and bite it but will let go as soon as he senses some resistance he lacks the tenacity of a good rottweiler or german shepard I have an English bulldog that will hang from a spring pole and hold like his life depends on it. He is very alert and attentive but very soft and at times shy and timid he whines and barks anytime he's left alone I know he's only 10 weeks but not something I expected after hearing all the hype about how much of a confident natural protector these dogs are. I initially got this dog to do some advanced protection training with but as of right now I'm not 100% sold this puppy has what it takes. I've seen a lot of these dogs bite and go crazy behind fences but I've seen poodles do that too. I'm looking for some insight from someone who has experience. Do presas develop that drive later on what can I expect?
