Oh, Erin makes a good point, and once you've been dragging your dog, then you also have to find a way to get them home again...
I found that to be a bit tricky with Oscar and his arthritis, sometimes he'll lag behind on walks, and we're out in the middle of nowhere, and he's a 75 lb dog (this is when I wish he was a "standard size" Pit Bull, so I could carry him).
I think probably the worst option for this situation is to not only have the dog get to the point where they are lagging behind (exhaustion or soreness) but to compound it, have to push themselves under this condition - this is where injuries and heat stroke come from
so, in other words, caution is key...
sometimes I'll take myself for a walk(and by walk I mean brisk-walk-strut- I hustle!), then come home and take the dog out, because I know on some days he can't go for as long as I can any more.
I can only please one person per day. Today is not your day, tomorrow doesn't look good either.
