I'm concerned about Solo. It's been three weeks since Rusty's been gone and Solo has turned into a different dog. He is no longer my "Silly Solo". He did start eating a few days after Rusty left us, so that was a good sign. The last two weeks though he doesn't seem like himself. I know this is kinda funny to say about a greyhound, but all he does is lay around. He doesn't do any of his silly little things he used to do. He's also had a little bit of an upset tummy, but that was less than 24 hours. He's also been panting a lot, but it's not been overly warm this week, actually it's been on the cooler side. He still wants to go on his walks, but a couple of times he only wanted to go a few houses down and then come home.
I'm wondering if I am just truly seeing his age now that old man is gone, or if Solo is really depressed. I feel so bad for him.
