Im in the same boat. I just adopted my 10 year old senior Chihuahua last August (2017) and she stands on three legs when she eats or goes outside to the potty. As of last week, its been super hard for her to get up in the morning without her joints locking up or going lame on her. Shes been tumbling out of her bed just to go to the peepad, also even standing to eat is so hard that she will tip over sometimes so we gently help hold her up so she can eat. From what I've been researching it sounds like she has bad arthritis or luxating patella. I made an appointment for her to see a specialist this week. If she needs to have surgery, I will do what I can to make her better, but Im not sure if shes even a right candidate as two weeks ago she started collapsing and was rushed to Emergency. We were referered to Cardiologist who diagnosed her with pulmonary hypertension and shes been on 2 medications (will need for the rest of her life)
She's so tiny (3.9 lbs) and fragile it scares me. Although we've only had her for 5 months, we love her so much. This little tiny old dog is the sweetest, and quietest soul it kills me to think of losing her too soon. The 1st week we brought her home from the shelter, she had to get spayed,10 teeth removed, bad infection taken care of. She was in so much pain and screamed when she moved around, or tried to crawl in our laps my husband was so upset with me for putting her through it. Im scared if she needs the LP, it will be excruciating for her.
Anyhow, we changed her food to Nature's Recipe (Homestyle) Easy Digesting wet food,
bought glucosamine granules to put in her food, and even researching CBD oils to help ease her pain. A few of our friends use CBD oils as a holistic medicine and its working great.
The below is our sweet Poppy
