Dylan went through a phase of picking up snails, there is a place in our garden where they congregate, but he grew out of it. We just went out with him at night to check he wasn't picking them up, as yes, they do carry nasty parasites. The phase didn't last long, thankfully, just puppy exploration.
Jayne, that is 🤮. Hope BNM isn't moving the problem on, but glad it seems to be working for Humph! We haven’t had any ticks yet, the weather has been so unseasonably cold and wet. I remember last time we were in eastern France and over in the Black Forest there were signs everywhere in the woods about ticks. They freak me out 😱🤮.
