Well we are not sure what is wrong at this point, but we were awoke at 3:30AM to a thud. And then another, and then another. We jumped up and found Tasha was not able to walk. She would try and then just fall. When she went to bed, all was fine thus this is very strange.
We got her out to the living room area and gave her a dog pain pill for her arthritis. We stayed up a about 1.5 hours and then moved her back into the bed room. This morning she is walking on her own, but not like before. It is like she is not stable at all. We are going to find a vet this morning after the RV is taken in. Will keep you posted.
