I have 3 very well behaved golden retrievers. One is 13 her name is Shania, then Scotch he's 10 and Bonnie their daughter is 7. They need a slow walk for about half an hour plus additional time out at the view point or water to sit and play around by themselves. Two walk by themselves only Scotch needs to be on a lead. They eat their food at around 11 or later. They have a snack at four and another walk/ outdoor leisure around Then just at home till sleep time if they are taken across for a last wee before you go to sleep. They don't bark unless someone visits the house. They Never get into any fights even when provoked by other dogs.
