I have a 2 year old chihuahua mix, she's about 6 lbs. In the last week she's begun to be very clingy, follows either myself or my boyfriend around and stays wherever we are, and has been very shaky. She doesn't usually shake. Today while at work my boyfriend said she stumbled and started rubbing her ear on the carpet, was unsure of her step, etc. She usually has a lot of energy. Tonight when I got home she was happy to see me, then just kind of clung to me. After dinner she was getting her belly rubbed and the she jumped down, put her top feet on the couch, acted like she was stretching and started to shake. She looks miserable and I'm really unsure what to do. I'm super broke right now and can't really afford them to run a while bunch of tests.
Suggestions? Please and thank you.
