All dogs have typically two estrus or heat cycles a year about 6 months apart that last 2-3 weeks
For a Great Dane, 9 to 12 months is not unusual.
Great Danes come in black, blue, fawn, merle, mantel, harlequin, and brindle.
In Beowulf, the Danes are a tribe ruled by King Hrothgar. They live in Heorot, a great mead hall that is attacked by the monster Grendel. Beowulf comes to help the Danes by defeating Grendel and his mother.
Reports artwork and artifacts indicate that a dog resembling a Great Dane might have existed over 2000 years ago. It is believed that dogs similar to the Great Dane first belonged to one of the tribes of Asia called the Assyrians. They used this dog to hunt wild boar and other large game. We can be certain that the Great Dane first developed and flourished in Germany but the Great Danes origins are not entirely clear. (the Germans took the breed and refined it)
Actually you can breed a Vaporeon with a Ditto. It will just take some time for an Egg to come out.
No, it's not. A Labrador can come in three main colors which are cream, black and chocolate the ones I seen anyway a lot of people in my area have chocolate labs and are such great dogs, the color chocolate is not a defect in this breed at all, its actually a well sort after color and my choice of colors in the Labrador's if you google the breed you will come up with alot of information on the breed including what colors are acceptable in a purebred Labrador Retriever hope this answers your question.
Dogs come in all sizes, From "teacup" Chihuahuas to Mastiffs, St Bernards and Great Danes that can weigh as much - and more - than an adult human male.
The Pitbull is a breed of dog. Brindle is a COLOR PATTERN that occurs in many different breeds. You'll see Brindle Pitbulls, Great Danes, Boxers, and Bulldogs. There maybe some other breeds I'm forgetting, but these immediately come to mind. Is not rare to see brindle color in pitbulls. As matter of fact is quite common.
you have to wait for them to come into heat If the female is in heat she will eventually come around.
Great Britain, France, Spain, Italy, Portugal and Russia. If you consider the Vikings to be Danes, then add Denmark to the list. Eventually, people from every nation have come here.
Bichons are a breed of their own, they are not a crossbreed
depends on the breed of dog and age. on average about once every six months.
That is horrible. If they did breed they would not come out tattooed.
