My dogs are barking

Man’s best friend

Let sleeping dogs lie

Lap dog

Hangdog expression

Hair of the dog

Gone to the dogs

Give a dog a bad name

Every man and his dog

Every dog has its day

Even the dogs in the street know

Doggy bag

Dog’s life

Dog’s dinner

Dog-whistle politics

Dog-eared

Dog tired

Dog in the manger

Dog eat dog

Dog days

Dog and pony show

Dirty dog

Crooked as a dog’s hind leg

Cat and dog life

Call the dogs off

You cannot teach an old dog new tricks

You can’t teach an old dog new tricks

While dog gnaws bone, companions would be none

Three things are not to be trusted: a cow’s horn, a dog’s tooth, and a horse’s hoof

They lead a cat-and-dog life

We may not expect a good whelp from an ill dog

Want a pretence to whip a dog, say that he ate the frying-pan

Two dogs over one bone seldom agree

Two dogs strive for a bone, and a third runs away with it

Trust not a horse’s heel nor a dog’s tooth
