My boy is an oldie (15) and has arthritis so only has short walks these days.
He gets up at 6.00 when dh gets up, goes straight out in the garden, then has his breakfast and meds, then goes out in the garden again. We sort breakfast for the family, then take him for his morning walk. All done by about 8.50.
He then sleeps until 10.30/11.00 ish, when he goes out for a wee and I walk him round the garden to get his joints moving. Then it’s back to bed, usually snuggled under a blanket, where he snoozes until 12.30 ish when he does a bit of brain training or has a a kong wobbler or lickimat.
Sometimes he gets a short walk with dh when he stops for lunch, but not every day. If he’s not walking at lunchtime he’ll sleep again until 3.30, when he starts demanding his snuffle mat and another trip to the garden. Then back to sleep until his dinner at 6.30 and another trip to the garden.
He has his last walk around 7.30/8.00 ish, has his teeth brushed and then back to snoozing.
He tells us when he thinks it’s time to go to bed, via highly perfected use of Paddington stares and lots of huffing. It used to be about 10.30, but as he’s getting older it’s creeping earlier and earlier. The last couple of weeks it’s been 9.40ish, so now we’re having to wake him up for a last wee of the night before we go to bed ourselves.
He knows his schedule and it’s basically driven by him. If he doesn’t wake up for something, we let him sleep, unless it’s been too long and his joints will be stiffening up, in which case we do have to wake him and walk him up and down the garden or round the house a bit. We find if it’s a really cold day he’s more likely to sleep through for longer, so we keep him wrapped up warm and get him to move around the house a bit, rather than dragging him out on freezing walks.
Dogs do need a lot of sleep and doing too much can over-stimulate them and leave them unable to settle themselves. If your dog is happy and settled it probably means you are getting the balance right.
