True, dogs aren't exactly a fertile market for self-help manuals. But a new study finds that the brains of male and female canines are not the same -- and in at least one task, the females have an edge.

Müller and his colleagues tested female and male dogs -- "completely normal family dogs," Muller said -- to see whether they understand a concept called "object permanence," which is the realization that objects don't disappear and don't change form just because they go out of sight. Children learn this physical law around the age of 1 or so. The question, Müller said, was whether dogs understand it too. [Read: 10 Things You Didn't Know About the Brain]
The researchers set up a wooden board and a system of blue tennis balls attached to strings. The dogs, 25 female and 25 male, watched one of four scenarios: A small ball disappearing behind the board and re-emerging; a large ball disappearing and re-emerging; a large ball disappearing and a small ball emerging; or a small ball disappearing and a large ball emerging. The first two experiments were the "expected" conditions, which didn't break any laws of nature. The second two events, in which a ball would seem to shrink or grow while out of sight, were the "unexpected" or impossible conditions.
There are three possible explanations for why male and female dogs -- or any animal -- might show sex-based brain differences. The first is that evolutionary pressures in the past might have subtly shifted male and female brains. If one sex hunts while the other builds nests, for example, the nest-builder might gradually become better at spatial reasoning, while the hunter might evolve to be better at navigating through unfamiliar territory. Another possibility is that brain differences arise because of childbearing duties; a female solely responsible for rearing her offspring might show greater nurturing skills than a male that has little to do with his offspring after mating.
TrainingThe majority of male dogs tend to remain rather child like, and they seem to take a little longer to mature. It can also be a little difficult to keep their attention when training them, but if you can work out what pleases your dog you can make training much easier. On the other hand, more male dogs have won dog shows than females so perhaps if you invest time into training him, your dog will prove all the neighbours wrong.
Good With Children?Some people choose a female dog over a male dog if they have children, because it is often thought that female dogs are naturally more protective of young ones.
TrainingIt has always been said that female dogs are easier to train than male dogs because they are far less easily distracted and this might certainly be the case, but if you look at the history of dog show winners a larger percentage of them are males. You should also note that female dogs are almost untrainable during the times when they are on heat.
Our Chihuahua is a female and has been fixed since she was 6 months old. She is 5 years old now. Sometimes when my husband and I are having sex she comes out of no where and jumps up on the bed quietly then goes to humping my husbands leg or tries to hump his arm. I mean serious humping and out of breath. It is the only time she does it. I have to get up and go put her in the bathroom with pee pads and water until we get finished.
We are currently considering adopting a male cane corso/doberman mix (his dna said 50% dobie and 38 cane corso, with italian mastiff and rottie) and your comment made me wonder if you know what your female is mixed with? One of the reasons we are not 100% sure about adopting him is because we are worried he will be huge! He is so sweet and smart, and we really thought he was a hound mix.
These are mostly reproductive disorders like pyometra, which mainly appears in dogs over 5 years of age; vaginitis, which is common in female puppies; and metritis, an inflammation of the uterus after pregnancy.
There are some health problems that only affect female dogs. One of the most common (and potentially life-threatening) is a reproductive disorder, pyometra, which mainly appears in dogs over 5 years of age.
The most inaccurate information which circulates around dog castration is probably the following: male dogs are castrated and female dogs are sterilized. This is not entirely true as the two can be carried out both on male and female dogs.
Dog castration means removing the glands responsible for hormone production. Testicles are removed in male dogs and eggs in female dogs. The following side effects could occur: incontinence and skeletal and/or growth disorders.
Yes, but not immediately after castration! After the first days of a successfully carried out castration, your male dog could still get another female dog pregnant. Due to the phenomenon of dormant sperm, you should carefully watch your dog when you are out on a walk during the first days after the surgery.
In the eyes of other dogs, your castrated dog is no longer the same dog as before. Whether male or female, your castrated dog is no longer regarded as male or female, but rather as a gender-neutral dog.
One study addressed sex differences in human APs through measurements on midmyocardial left ventricular myocytes from explanted hearts in end-stage heart failure (85). Despite concerns regarding the health of these hearts, APs from female myocytes were significantly longer than in males, consistent with longer QT intervals in women. There was also a trend toward larger ICa,L and smaller Ito in female compared with male myocytes, which did not reach statistical significance because of cell-to-cell variability.
The lagomorph or, more precisely, the New Zealand white rabbit is a frequently used strain of animals. It exhibits similar sex differences in LQT2-related arrhythmias as in humans, for both adult and prepubertal rabbits and approximately the same combination of ionic currents underlie rabbit and human APs. At rapid pacing rates, there are no sex differences in the rabbit ECG, but sex differences are revealed at longer cycle lengths (21, 33, 44, 96). The rabbit exhibits significant sex differences in response to drugs (48) and has longer ventricular APDs in females than in males (65, 84, 96). An important difference between humans and rabbits is that rabbits are inducible ovulators and they lack a menstrual cycle that is often considered to be a valuable advantage in studies of female hearts with constant levels of sex steroids. For these reasons, sex differences have been extensively studied in rabbits as the most appropriate animal model to study sex differences in cardiac electrical activity.
"Unlike cats who are fertile every 21 days, dogs only come into heat twice a year. From an evolutionary perspective, the copulatory tie helps them make the most of every opportunity to produce offspring," Marty Greer, DVM, author of Canine Reproduction and Neonatology and co-owner of Veterinary Village in Lomira, Wis., says. "It improves the likelihood that semen reaches the eggs by pushing it forward and acting as a plug to keep semen inside the female."
Dogs remain stuck together at the end-stage of mating for five to 45 minutes, says Greer. The male dog dismounts and ends up rear-to-rear with the female. Dogs new to mating may experience a bit of anxiety at being locked together, but it's a natural process. Help your dog to remain calm and stand still until the two can safely separate. This will occur on its own once the male dog's arousal subsides.
It's rare, but not impossible for a neutered dog to get stuck when pairing up with a female. "It's more likely if your dog is recently neutered. That's because he may still have higher testosterone levels than he will later on," says Greer. Testosterone increases a dog's sex drive and affects the swelling of the bulbis glandis. However, even with less of the hormone, your dog can still become aroused, have intercourse, and end with a copulatory tie.
To prevent unwanted pregnancies, keep male dogs away from fertile female dogs so mating doesn't take place. "A female is potentially fertile four weeks after the start of her heat cycle," notes Greer. "When the bloody discharge dissipates, that's when she's most fertile."
But do remember that keeping a male dog from a female that's in heat can be difficult ... very difficult, sometimes. Dogs on the scent of a mating-ready female have been known to knock down people and break through doors and crates. The only foolproof way of avoiding pregnancy is to spay or neuter your dog.
Autosomal just means not sex-linked. Every dog has two sex chromosomes, females have two X chromosomes and males have an X chromosome and a Y chromosome. Any gene that is not on one of those two chromosomes is considered autosomal.
About the dogs, where do you get them from? Do they live in the club? Are they especially trained to have sex with people?There are special dog farms in many countries that train dogs to do just that. I know at least two of the kind in Russia. I personally work as a trainer in such farms in Germany, Belgium, and Sweden. They employ me to help the dogs get used to the human female. After about half a year of concentrated effort, the dogs fuck like devils and I love it. Of course these special dogs aren't cheap at all. I also have two dogs living in my cottage and they have never fucked with other dogs, only with humans. Often the clients will bring dogs of their own, these are of course trained dogs, too. They bring the dogs to the brothel?No, only talks and presentations take place in our club. The rest happens at the clients'. They all are well-heeled and have huge houses. There are dog enclosures and special basements for BDSM. They look like the basements Gestapo used to torture people in.
The females are not usually receptive to the male before the bleeding stops. Letting him mount her multiple times before she was ready has possibly changed her attitude toward this particular male. You should let our veterinarian examine her to confirm state of heat cycle. If necessary, he might prescribe a tranquilizer to help with accepting the male. 350c69d7ab
