I just moved today and I’ve been having trouble with my 10 month old puppy. He went to bathroom (pooped) before we left the house but anytime we stopped for him to get out and go he didn’t. I’ve also let him out multiple times when we got to the new place and he has yet to go. I didn’t give him food this morning due to him getting sick on car rides and it was a 5 hour trip. Is this normal? Also he is eating and drinking as normal
