Yes i think he'll miss you. He will notice you are not there but don't worry he has his mommy. My bf's sister has a dog that she barely acknowledges
But her parents were here for 4 months and the dad payed so much attention to him and spoiled him. He would sleep near them and look for them but now they're gone, they left yesterday and he looks so sad! I feel really bad, we pay a lot of attention to him(my bf and i) but he still is sad
