We had to go away for 3 days on a trip and left Laddy with his older skinsister. They have a one year old adorable male chihauhau. We were so worried the whole time we were gone only to come home to a puppy who didnt act one bit excited about seeing us and has moped all day today and wants to sleep and ignore us

. Is this normal behavior? Daughter said he and little sam (their furbaby) played the entire time.
