Dog acting weird after vacation?
I have a 3 year old Chihuahua. I adopted him about a year ago. He has grown quite attached to me after our time together, just as Chihuahuas typically do. I went on a vacation for one week and left him with dog sitters in their home. These sitters used to foster him for several months, so I felt he'd be more comfortable there as opposed to at the vet. When I went to go pick him up, he acted like he didn't know me! He shied away, sniffed me a little, but then would retreat. He did not run to greet me or act excited at all. I suppose my ego is a bit scorn haha, but I also have never experienced this behavior before with any dog.
Is it because my scent was different? Did he attach himself to the sitters and forget about me? It's been a day and he is acting more normal, just a little less cuddly. Any insight would be appreciated.
