I can only share my sympathy and empathy, as someone who has also had to "put down" a beloved canine on two occassions.

It ripped me apart, too. There is no reason not to mourn a beloved pet every bit as intensly as a beloved human.

The solace, as has been said, is in the knowledge that in sharing that love for however long it was, you added net positives to the universe. That certainly counts for something.
