Types of chihuahua

While the fascination of chihuahua, one of fonder explained the family of three Chi Babies as Maxwell, (6 months) Milo, (9 months) & Matilda (also 9 months) stating that while Milo & Matilda may be described on the bigger side of the Chi scale at 7 & 9lbs and the latest edition in the family, Maxwell is on the more of an average size at about 4 1/2lbs. 
By nature, it was observed that Milo, a bit more on the lazy side compared to the other two & sometimes will just sit & watch the others play. He is also a bit insecure which we are working on with him. They are all very loving but always anxious to share kisses with their owners' paradise. Sometimes they'll lie in the sun bathing and facing each other and making sure they are all looking their best. 
Many times, they will burrow in blankets, pillows until they fluff it up just enough to get comfortable & then proceed to take a long nap. While none of them are the pure from dog family, our female, Matilda is by far the bossiest out of the group. If she wants to play, you'd better play or else you'll get a "donkey kick" until she gets a reaction. Typical female! and yes, I can say that because I AM a female!

The another fonder of pet animals while sharing the experience mentioned that he was always a big dog person and do not know much about little dogs However when wanting a new addition to our home, he did his breed research & found the Chihuahua to best suit his wants in a dog. Apparently they surpassed the expectations as they went from one to three Chihuahua's in 3 short months with absolutely no regrets."

On recent TV show of pet animals many patrons have started using lot of the techniques.

While these puppies are still young and they are growing, most of these techniques will help them become balanced adults. Of course, the more any body watch such techniques, the more you learn trying to better teacher had is having progress. These pups are already great minding as an example of that as you can see, they are easily "pose-able" for photographs. 
Historically, dog descended from wolves, and deep within the psyche of your dog lies instincts of killing. 
Your dog depends for its survival and has learned that it must cooperate through thousands of years of evolution and adaptation with human society. The first domestication was the wolf. About twelve thousand years ago we discovered that having a wolf as a "pet" was a great asset. Men could hunt alongside and guard as they slept.
Of all the animals that we have domesticated, only the dog has willingly allowed itself to accept the authority of man without constraint. But it still retains the instinct to test its position. Yes, even sweet little Lady, the Maltese lying at your feet, has the genes and instincts of the wolf.
Wolves live by rules and have a social structure. The entire pack cooperates under a single leader. Lines are clearly defined. The leader of the pack eats first, and then the rest of the pack can eat. When your dog growls while eating, he behaved as the leader to eat first and ex pacts others to wait.
