I love spaniels, DW not so much so. We have two toy poodles who could not be better travel companions. They take up little space, don't shed, and lay quietly until they need a pit stop when they get restless. One at 13 has gone totally blind and has started to cry when separated from DW who got her at 8 weeks. The other, a rescue, is pretty much deaf. We think she is a little older. They are both great with kids and strangers.
Both are showing signs of enlarged heart which is an issue with this breed, it presses on the trachea and causes shortness of breath. We will just keep loving and spoiling them as long as possible.
