We've gone though the process five times as we've repeatedly outlived our furry companions. All except one were Labradors. Our current two, who are both rescues, are 11 and we expect to go through the trauma a couple more times in the next 2 - 3 years.
At our age, controlling 75-lb dogs can be tricky, particularly as you inherit whatever training (or lack thereof) has occurred. One of our current pair had been deposited at the Humane Society when we adopted him, and he was only five years old. DW had rotator cuff surgery as a result of him chasing a cat last year, as a demonstration. We can't imagine any dogs other than Labs being in the family, so we've decided that at 73 (me) and 70 (DW), these two are probably the last ones.
