Yes, it is a real bummer.
There was a little dog at the same kennel too ... Benji - he was a timid, sweet poodle cross. The owner left him for a 3 month stay and we had to give him special attention because he wouldn't eat unless he felt loved.
we used to bring him up to the office during the day and he would follow us around. It was my job to put him back in the kennel at night - he hated it big time, it was so sad.
This time the owner didn't come back for Benji, we tried to find the guy but it appeared to all of us that the dog had been dumped. I ended up taking him home with me! It was a dream come true for both of us...
But I had him for about 6 months, when suddenly out of the blue the owner came back to pick him up!
That was REALLY tough, and you know i always wished that i had tried to visit him and find out if he was happy..
BUT having said all that, i now have my own little shaggy black mutt -a very similar dog named Pippa. she's 100% pure lap dog who was left to me by a dear friend who passed away. Pippa goes with me everywhere and hates to be left for even a minute. She has the best life, even sleeps under my bed covers. Yet she can put on the best "sad sack" act you've ever seen, nearly everyone who meets her wants to take her home - she will go up to strangers in the street and will get into the visitors cars when they leave. If i leave her outside for too long she will escape the yard and go and sit on the neighbours doorstep and pretend she is lost...
