Standard poodles are any
Standard poodles are any poodle over 15 inches at the shoulder, although most are around 23 to 26. They have a lanky build, so my girl is 23.5 inches at the shoulder, but only 43 pounds. Since they were bred for the same purpose as Labrador and Golden retrievers, they have the same temperament, although I'm told S'Poos are calmer (mine is still a wild puppy so the jury is still out on her, LOL.) They are very intelligent, like a German Shepherds, (I've known several people that have had both). The major difference being that Poodles have hair, not fur, so they need to be groomed but do not shed.
We got a poodle because we have allergies. Since hypo-allergenic only applies to a clean dog, mine gets a bath every 7-10 days. I do a little grooming after each bath so it isn't such a huge project like doing it all at once. Home grooming isn't all that hard and most people with pet poodles don't bother with the fluffy head and tail or long ears.
S'Poos also come in prints and stripes, called Party poodles
Although having more than one color is considered a fault in AKC. These are a pair of "Party" poodles in non-frufru hair cuts.
Poodles
love water and even have webbed feet. I know people with S'Poos that are highly competitive hunting dogs and dock divers. They are also
fantastic with kids. (Those highlighted parts should be links to youtube videos.)
Excellent working dogs, entire teams of poodles have done well in the Iditarod
There are people that breed big poodles, sometimes called Royal (although it is not an official designation) the male Royals can be nearly 30 inches and 100 pounds, but I've never seen one that big. There are also breeders that specialize in Klein poodles, who are on the smaller side, 16-20 inches.
They are super affectionate and playful. They love to perform and make people laugh which is part of why they were popular for circus dogs.
I spent a year researching breeds before choosing a standard poodle and have never regretted it.
The best place to learn about poodles as ask questions is the yahoo group
http://pets.groups.yahoo.com/group/standard_poodle/
That is where I learned the most and learned how to groom. Many of the participants on the forum are breeders and rescuers and can help you find a great dog if you decided to get a S'Poo.
