It looks like something is trying to escape her face , like botflies or a PredAlien.
The autistic side of me wants that dog. Twinkie. My ex has two Chihuahuas and they are loved and healthy and exercise and play and get treats and outside and harass a cat. When friends visit with dogs they have a good time. Usually Chihuahuas are kind of assholes but these dogs were loved hard from day one.
Chihuahuas tend to "imprint" to their one human and tolerate others. Sometimes they love others unconditionally like in my case (remember is ex). That poor pupper only knows stench and misery and yelling and overnight shenanigans. Fuck.
The fan : I wouldn't personality hate on it. In the south east a lot of our back patio party areas have them built in or remodeled with , because it is to push away the humidity. I know in Hambers case it's both for cooling and stench control. Odd, she seems to have one going all the time lately.
