How often do you travel with him? I know when Maddie was little, I took her everywhere. Even if I was just running out for a few minutes. I was too chicken to leave her home alone.
I took Cooper in after she was 4-5 months old and she had trouble adjusting to car rides. We started with short trips to my moms. She eventually got to where she loves to go and only gets nervous when she gets in the car alone, she knows it is either vet or groomer. LOL
Our new pup get sick when he rides on curvy or bumpy roads. My dh read somewhere that pups often get sick in the car b/c of something with their inner ears is developing. ?? I am not sure...I can't remember crap.
