I'm new to pigs so I'm not sure how dumb this is going to sound. I have two hampshire X yorkshires. One, Cartman, gets coughing fits and limps. He seems a little sluggish but eats well. Yesterday he seemed to be getting better, never heard him cough in the 6 hours I was near him. Today, when he coughed semi-loose stool came out. He coughs for maybe 30 seconds every half hour or so. I've been giving him tetracycline in his feed according to the label directions, for four days now. I want to get a better look at his leg and doctor it if need be but he won't let me near him. He will allow the foot to lightly touch the ground but he won't put any weight on it. I tried using this snare kind of thing on his snout but it just comes right off. I read somewhere that that is the proper use of a snare. Is it? How agressive should I be in catching him? He weighs about 140 pounds (hard to tell for sure since he doesn't like being handled). How do I keep from being bitten and if I do get bitten, how bad will it likely be? Will the other pig attack me if Cartman squeals? How likely am I to mess his leg up worse trying to catch him? Is it worth trying? The other pig is fine.
