question on presa DNA?

So I am thinking of rescuing a Presa Canario from the shelter, I am taking him in tonight so I can evaluate his behavior with my family (fiance , chihuahua and cat) we previously owned a seriously Dog agressive Pitbull(no papers) but the pit was able to get along with both the cat and the chi just fine, outside he was crazy.. anyhow, the people that run the shelter showed me his papers and in one of the vet documents they ran a dna test to see what the dog was, and it showed 25% coming from bullmastiff/bulldog and 12.5% from boxer the rest of the DNA is unknown. Has anyone ever done a DNA test on their Presas and also what can I expect from this mixing that I see on his DNA panel? Here is a pic of the dog by the way, he is 11 months old and weights 115.

He looks like a Presa they are one of 4 breeds that don't have a DNA profile http://en.wikipedia.org/wiki/Presa_Canario They have been revived since the 70's with foreign blood the 12% would probable be the parent breed the Majorero here is the profile on this site http://molosserdogs.com/e107_plugins/content/content.php?content.857. Looks like a fine dog with training he should work out I'd keep them separate for the first few hours let everybody cool off a kennel would be good they can sniff with little worry of the big dog stepping on the little one, I did this when we got a small puppy I locked the big pup up to mellow her first they are great together. I would take the Presa for a good walk near your house and in your yard first best of luck.

BUMP

So now we know presa origins...

is that a sarcastic remark? I am just trying to figure out if this is a presa or a dogo and what I should look for as far as behavior for a stable dog with good nerves.

A stable dog hard to tell on the first day or form a computer but things to watch for are does he look away, lick his lips or his eyes start darting when someone bends down to pet him if he does he may be shy possibly leading to a bite. Drop something loud like a pot or pan 10 feet away is he skittish, neutral or comes to check it out skittish is no good but let him get use to the house first. Try him on different surfaces see how he reacts then try something unstable like a box or bridge. When you walk him see how he is with passing dogs there are endless scenarios he might fail at first but will improve with training and trust. One thing I do recommend is playing settle with him you get him to lay down or go to him when he is laying down with some treats and pet him while giving him treats and saying settle after you have done this a few times and he stays put and you trust him get him to lay on his side giving him treats petting him saying settle till he will stay there as long as you want he has now submitted to you can use this to cut his nails take him to the vet and transfer authority to your partner or kids with your direct involvement saying settle they soon lay down without a fuss if you are constant my three year old can do it to my dog now. I sold a rottweiler to friends 15 years ago and when the dog was 9 months old he bite both there kids they always play fought with him but not he was growing up he was taking over I went over and taught him settle I got the 3 & 10 year old to do it the 3 year old would do it all the time looking the near full grown rottie in the eye grabbing his face and rolling him over so she could sit on his head he lived another 9 years they never had a problem again he was a great guard dog. It can be used for dog aggregation also. As far as dogo or presa I don't know dogos have no weight limit males should be 110pd's minimum http://molosserdogs.com/e107_plugins/content/content.php?content.465 presa's do have a weight limit in Spain but not the UK they have a 100pd minimum no max but they both allow the color black http://molosserdogs.com/e107_plugins/content/content.php?content.2821

Awesome I actually laid him down to take cookies so my little dog could feel more relaxed to come out and smell him. THey both seemed to be ok once he was laying down and he looked a lot taller. I will def try to do a lot of that laying down scenario. Are they supossed to drool a lot? this dog drools constantly, someone told me taht they pant and drool when they are stressed. What is your view on that>?

They can pant and drool from stress, excitement or heat the panting will go away but the drool is pretty steady good to hear he is fitting in and accepting you and your dog don't push it to much yet go slow build trust but . Condition the word settle into the game you can do it from a distance and even if he doesn't lay down he will still settle down, keep us informed were here to help.

It was not a sarcastic remark. I don't know the specific breeds behind the presa nor the percentage of each breed. I only know about the majorero and bulldog and some bullmastiff blood into the presa. Some people claim that some lines used bullterrier, great dane and fila. But i don't know for sure.

Things arent going as well, the dog is extremely stressed out without his foster. He wont stop panting and looking for it, when he snaps out of that he flies onto the couch and keeps testing me. I had to throw him off me couple of times, he also does not want to eat and he stayed up all night crying and panting constantly... I don't know if getting him crated and keeping upstairs with us will make that go away. I am completely in shock that the previous owners never taught this dog any commands, I mean what the hell were they thinking? the only thing he knows is sit, besides that he wont stay on his bed and he just keeps pacing around.

I'd suggest walking him as much as possible it will burn energy and start to form a bond with you. Kennel him when you can't watch him toss a bone or treat In, only a few minutes at a time but only let him out when he is quiet it may take awhile but that is most important. The kennel will be his safe place he will like it he probably has already has been in one and may miss it his den. I'd start training the sit, down, stand at the same time one after another with food so he starts paying attention and listening guide him with food you shouldn't be heavy handed now he is in transition. Take him around the block as much as possible even for a few minutes to change his focus see if he will retrieve something in your yard only. Start taking him on walks with a 20 foot rope or leash in a field you are like a train he can sniff run whatever but when he hits the end of the leash you keep going with out jerking he will start watching where you are, do that for a week then start training the heel . In a couple of days the pacing will stop he will calm down or sooner.
