Ruby just freaked me out... she has never done this before > We were just playing fetch (it is moderate to coolish today). Several times when she brought the ball back, she appeared to kind of start to tip over and lean to one side enough to need to catch her balance and readjust her feet. And then when she went for water, she twice tipped forward enough to bump into and move the plastic table I have over the bowl (bowl is centered under a little outdoor table). She kept wanting to play and seemed to run in a straight line and catch the ball properly but I have never witnessed her lose balance like that ever.... She did not act distressed or like she was concerned/confused in the least. We were playing less than 10 minutes, too..... She tried to make out with me when we came in and she seems otherwise fine but I'd like to know if anyone has seen this as a random event...???
