Not really that worried, more interested. But yeah, parasites are always a possibility.
Oh, did I tell about our elk encounter the other day? The dogs started barking on our walk, but we didn't see anything at first, until we spotted a young male from last years batch lying about 20 meters from us. It wasn't reacting to anything, so we thought it was hurt. I held the dogs while Karin went a bit closer to take a look at it (We didn't want to call the hunting club in case nothing was wrong with it, as it probably wouldn't have been there anymore by the time they got there). She couldn't see any wound, so she started to circle behind it to see if there's a blood trail. When she was about 2 meters from it, it got up and faced her. Now, I don't know how close any of you have ever been to a young male elk, but 2 meters is definitely less than what anyone should feel comfortable with. Luckily there was a fallen tree between them, she kept the roots as a shield in front of her. Every time she took a step back, it took a step towards her. Finally, after 2 minutes of staring at each other he turned around a bit, and Karin managed to back out quickly with her tail between her legs. Talk about an adrenaline rush.
