We try to make sure that we visit PIL s every week, at least once a week. Id like DSs to see them more often TBH especially as they see my parents 2-3 times a week, sometimes more, but with work etc its not always easy.
However, we always visit them on a friday afternoon, as it is the most convenient time for both of us. Well last friday when we went, we were only there for 10 minutes and FIL announced that the dog needed walking, he put on his coat and off he went.
DS1 was upset by this as he loves to go play with his grandad. I thought he might ask DS1 to go with him (DS2 is only 11mo) but he didnt.
An hour an half later, he still hadnt returned and DS2 was getting tired so we had to leave. We asked MIL if everything was ok and she said everything was fine but FIL does like to make sure the dog has had a good walk before it gets too dark. Nothing was said before hand to upset him for him to just up and leave. The only thing I can think of is the dog was getting very restless (its still a very young dog) and boistrous and yes, it probably did want a walk, but couldnt it have waited until we left?
They only see their GC once a week for a couple of hours, I was so upset that he put the dog first. We went home with a very upset DS who didnt get to play marbles with his grandad 
AIBU?
