DETROIT (CBS Detroit) Think dogs and cats don’t express how they really feel? Think again.

Because a glimpse of our pets of the week shows not only do their wag their tails when they want to charm — they also smile.

Take, for instance, Little Red, an 8-year-old Chihuahua who shows his teeth with a big, bright smile. He’s a lapdog who enjoys being petted. Then there’s Meka, a sweet little girl who loves attention and can’t wait to say hello.

They’re both smiling in their pictures this week — but there’s one thing that would make them smile even bigger: A forever home!
