If I leave the door open on my 500 the two dogs will stay in it all the time. If I take one step towards the shed where the SXS is stored, both take off in a dead run and sit by the door waiting for me. Black one is Dixie,an 80 pound Catahoula, red one is her daughter, Rosie,60 pounds of 1/2 Catahoula,1/4 mountain cur,1/4 bulldog. They like to ride in my truck, the SXS and the wife's golf cart. I bought the 500 in 2014, Dixie wasn't born until 2015, so she was raised around it, as was Rosie, there was never a time they didn't want to ride in it. When Dixie was 10 months old she was in the cab of my truck when we had a really bad truck wreck, hit head on by a 3/4 ton truck estimated to have been going 60-70mph, we were sitting still in a turning lane. Anyway how we both survived is a miracle, but she refused to ride in a truck again for about 6 months, now she will, but it took a while.
