u can get cheap electric can openers now.
also, for a while i used alpo patties that came wrapped in cellophane instead of wet dog food. the dog did not complain.
for those jars that would not open i used an oil can wrench.
if washing dishes with one hand cook things that don't get the dishes quite as dirty. use the dog to do a pre-rinse.
query: for the massager that does everything, which setting does the most good?
