  1. Everyone, please remind those with dogs to be extra careful with how much time their dog’s paws are on the cold ground. It doesn’t take long to do permanent damage, watch for them lifting their paws up, it indicates discomfort and they are telling to they’ve had enough.

    My monsters wanted out this morning and Lily and her tiny toes were limping from cold in less than 5 minutes.

  3. No doubt Jamie, I have 2 big dogs, a German Shepherd and a big mut, and it’s the same with them, couple minutes and the limping starts. The poor babies. Some dogs don’t limp as much like that, but you can bet they still freeze. So don’t forget them outside like we can do sometimes, it can turn out very bad for them. Happy new year everyone!!
