Carino weighed in at 4.7 pounds today, and Pepito weighed in at 3.4 pounds. The two brothers could hardly look more different except that they are both rare blue in color. Carino is rangy and tall with long, lanky legs. His ears stand up tall. Pepito is petite with soft curves, short legs, and floppy ears that blow around in the hot summer breeze when we go outside. He may be tiny, but he is feisty and often instigates wrestling matches with Carino. They both love snuggling with me and with each other.
Housetraining is going slowly, but it is progressing. My husband, daughter, and I are all vigilant when they have free time and try to catch them in the act or preferably when they start sniffing and circling. We rush them outside—always to the same spot— or to one of the three indoor potty patches. This does not seem to confuse them because we alternate spots often. I want to be prepared for inclement weather episodes so we don’t make sudden changes. There have been fewer and fewer “accidents.” YES, Chihuahuas CAN be housetrained!
”We’re not too sure about this place. What does booster shots mean, anyway.”
Our Dr. Ashley Stricklin of Kerrville Veterinary Clinic (https://kerrvillevetclinic.com) advised me last weekend that boys are much hard to housetrain than girls. I don’t know why that is. No matter the gender of the puppy, or the breed for that matter, the keys really are vigilance, persistence, consistency.
Dr. Stricklin advised me also that the boys now were old enough at three months and had enough weight to begin having meals three times a day rather than being free-fed. Our schedule has evolved, but it looks something like this: 7:00 out of their little house and out to pee and poop, 7:30 breakfast of kibbles, 8:00 food taken up and out again, 8:30 free run of the house to cavort, 9:00 nap time and snuggle with me while I read, 10:00 practice obedience skills, 11:00 out again and then into big playpen while I get ready, 11:30 lunch of kibbles, noon out again, 1:00 off to yoga class with me. They have a car seat but are still so small that they jump out, tethers and all, so we are improvising for the moment. 
I take them out before and after a yoga class, and they very sweetly sleep through class for their afternoon nap time. People are always commenting on how quiet they are. I attribute that to intensive socializing we have been doing. They like everybody! On days when I am home in the afternoon, we enjoy nap time snuggled up on the bed. The schedule does vary somewhat on some days depending on my yoga class schedule. At one of the studios where I teach the owner has instructed me not to bring them any more, never mind that they stay tethered in their stroller and absolutely quiet the entire time. She said some people might be allergic to or afraid of dogs. Oh, well, it’s her house—her rules. It’s sad, though, because my students love them. They have dinner between 5:30 and 6:00, then outside to take care of business matters, then back inside for play. Evenings are my quilting time, and they curl up on a blanket by my feet with no urging from me. I wrap one of my old sweaters around them. They just can’t seem to be very far from me, and I love it that way. 
Obedience training has focused on the sit command and leash training. Smidgens of peanut butter on my index finger have been my best tool so far. They still are not crazy about the leash but have stopped acting like bucking broncos! We may do another week of sit before I move on to the down command. Sessions are short because their attention spans are as tiny as they are.
All in all, they are quite delightful and keep us laughing every day. We love them so much. Getting the two of them was the right decision.
