H, I am new to the forum and I have a 3 yr old female called Molly and a 2 yr old female called ruby. Ruby absolutely loves belly rubs anytime of the day and will roll over for a love. Molly only likes them when she is in the mood, usually first thing in the morning when she wakes up next to me or last thing at night while watching TV with my husband in bed - she is a daddy's girl. I guess you have to do what works with each individual dog, neither of mine are aggressive at all, so plenty of belly rubbing in our house. I think ruby wouod die of emotional abndonment LOL if we took away the belly rubs!!
