I have a one year old white silkie. She was perfectly fine yesterday. She foraged, walked, ran, went to bed as usual. This morning I noticed when it was time to let them out for the day she was sitting down and appeared weak. I tried to get her up and she can't walk very much or far she just lays down or sits. I put electrolyte water out for her and she is drinking. I offered her oyster shells and food. She wants neither. What is wrong? Should I give her some nutri drench?
