help i have a two year old labrador who gas just started to constantly cry
he has recently been to a dog sitters while we went away forfour days, there were two other dogs there with him, since he has come home and been the only dog he just keeps on crying.
we take for a good hour walk  every day and spend lots of time playing with him.
could he just be after more of our attention or do you think he could be pinning for his doggy friends?????
help and advice greatly received.

As you said he is probably pinning for his new friends, poor baby.

Warm regards Susan.
