dog sitting

ROMO - is tired and seems depressed. He lost both of his companion dogs last month. A Great Dane & his playmate; a Jack Russell passed away last month. The Great Dane passed from illness and age. The Jack Russell escaped with Romo but didn't return (hit by car). I'm dog sitting Romo and his 2 new rescue companion dogs because my daughter was leaving town and we thought it would be best for the dogs & one cat to have a full time sitter. Romo is not as energetic as the last time I saw him. He is either sitting next to me or curled up on the couch & doesn't play with the new dogs like he did with the Jack Russell. Took photos of all 3 dogs resting but not together and I can only post one.
