The snow around here is finally melting and so there's actually ground underneath! I waled Tal for a while today, then took him to play fetch. He fetched, but was more interested in sniffing around! It's not like it was a new place but I couldn't imagine what it could be since we have been covered with lots of snow.
As snow melts, do your labs do this...seem more interested in sniffing that fetching?
We have lots of snow here so I can't really comment. Maybe Tal is trying to tell us spring is in the air... or in the scent!
No snow here so I'm no help. ;D
