dogo argentino/german shepherd mix ?

Like J C says, it's a matter of genetics and the genetics of GSD are impossible to be extinguished. Even if you mate her with your pal's purebred Dogo, the puppies will never actually be purebred Dogo since their mother is a mix and not purebred. The genes function in different ways in each dog. Your own dog may not evolve GSD characteristics, but you mustn't take it for granted that the pups will gain most of their mother's genes. Genes are transferred, so it's likely that the GSD's genes are transferred to the puppies regardless the fact that you Dogo/GSD mix mated with a purebred Dogo. Genes can be transferred even up to 7 generations.

Also, your dog is too young so, the fact that it has just a couple of brown GSD hairs now, doesn't mean it will remain that way. She will grow up and her current characteristics will be altered. She may become even blacker with just some pale,white spots and not brown hairs at all or these brown hairs may become even more and the dog starts gaining even more GSD characteristics - you can't really figure out a dog's appearance as it will be finally formed later on. Yes, the truth is that right now she seems just a Dogo mix, if you asked me I wouldn't suggest GSD mix at all, but see? - it's genes again that play their role and the GSD's genes may evolve when the dog grows up or remain the way they are.

Now, concerning her character, it's something which you will find out later on as well. Surely the dog will gain characteristics of the personality of both breeds, but I can't tell you whether they will be good or bad. It depends on genes as well - some dogs inherit bad characteristics or even the worst from their parents and others inherit good or even the best. You'll find out later on, when she grows up.

It's up to you to make her a well-behaved and sociable dog. Of course, the breed plays its role that's why I feel the dog may appear to be dominant or aggressive at times, but it's not always bad. If handled properly, these instincts can be taken advantage of and be turned into characteristics like territorial protection and generally, protectiveness of you (her owner) and her territory in general. If an owner is knowledgeable,willing to occupy with their dog and experienced, then it's good because they will be able to control the dog and train it better. When she grows a big older start taking her to dog parks from a very young age in order to get used to socializing with other dogs/people,take her out for walks in general in order to introduce her gently to the presence of people and dogs around her. Dogs that are not socialized from a very young age(from 3 months old at least), end up becoming either too shy or too wild, due to not having regular contact with other beings around them. If you start now, then no problems later.

You can also buy some good dog training books or even better, ask for a trainer to give you advice and more analyzed information on how to handle and properly socialize your dog. It's always effective!

Best of Luck ?

ps she's very cute!

It's all up to genetics what she will be like - temperament is inherited the same way that color, size, etc. is. What you can expect in terms of size/color is a bit unpredictable - at this point you cannot tell what genes she has inherited from both parents. Some dogs inherit the best genes from a mix, and others inherit the worst genes. You can say though that you are going to have a large and powerful dog, that will need a firm hand with training and early socialization with both dogs and people. Hopefully you will not end up with a large and aggressive dog with hip dysplasia - that would be the worst of both breeds.

Mating her is pointless - the dogs will never be Dogo, they will always be a mix. And that second generation could even get you dogs that look more Shephard than Dogo. Get her spayed when she is about a year old, then you don't have to worry about it.

She is a very cute pup, BTW.

the dog might get the best of both breeds or the worst of both breeds, if you go by likelihood probably end up average. The dog might also end up confused as to whether it is a hunting dog or herding dog.

Since you have told us nothing about the quality of either parent, we don't know if the parents were any good and had any good genes to pass on.

Rest assured if you breed your 50% mix with another dogo you will end up on average with puppies with 25% German Shepherd genes, though an individual puppy could be anything from 100% dogo to 50% German Shepherd.

Cute looking puppy or not, who in their right mind would do this combination, or need to!

She's not a breed, she's mix-bred, for starters and regardless of who you might think about mating her with (so don't!!) her offspring will still be mix-bred.

As there's no Breed Standard, how she'll eventually be is a total unknown. And this applies to size (much as she's not going to be small), temperament, coat, health (yes) and longevity. All you can do is rear her sensibly, and get her into a good training class once she's old enough.

And get her spayed before she gets caught and produces even more mix-bred puppies.

ps Just to add although it's to be hoped this puppy will be carrying the best of each breed, logic suggests that as this kind of breeding is done for one reason alone - and that's not for anything other than INCOME - no testing will have been done and most likely the parents were sold as pets not top quality animals, it's more likely you'll have a puppy with all the problems each breed has. Starting with hips and elbow problems!

Puppies can also get the WORST of both breeds too, which also includes the medical issues both tend to have.

No dog 'loses genes', they're born with them and they keep them.

And yes, the dog will be aggressive, that's what's bred INTO the dogo breed. It's up to the owner to train their dog in proper behavior and watch for issues. If your dog bites anyone your city may require the dog to be put down based on the breed mix you have.

Fake vet alert! You know who I mean.

Your dog can just as easily inherit the worst characteristics of both breeds. Nobody in their right mind would breed these two together and nobody in their right mind would buy the offspring unless they wanted a catch dog that was too intelligent to get itself hurt and therefore useless.
