I have a calf that turned 2 months old today. About a month ago she had a knot on the inside of her knee. I gave her two rounds of LA200 and put her in a pen with another pair so that she did not have to travel out in the pasture. Took her to the vet last Friday and she vet put a sweat wrap on the knee to help lower the swelling. The vet thought maybe joint fluid but did not want to tap due to infection possibilities at the site. Now the poor little thing is buckled on both knees. Nurses, eats grain and jumps around a bit but when she stands it like she wants to go down on her knees. Is there anything else to do???? Should I have her put down??? The vet is coming back later this am.
