I've been doing an online search about them since yesterday. I spray their yard often to keep fleas and ticks down so I know I'm keeping the skeeter back too. We were at Sardis in October. They were in their pen, I went to change the water. Luke had a few skeeters on him, I sprayed him with Off not to get it where he would be licking. Then spread bug powder around the pen. To late I guess.
Trying to figure out why a vet would treat them for one year and nothing said after that.

Not the testing but the treatment is $1,000., 5 to 10 treatments needed in stages 2 and 3. Stage 3 and 4 their poop is black, blood. Their pee is brown to dark brown, blood.
