How can I get rid of the dogs on the steps?

Patience. They'll leave eventually.

Meanwhile, why don't you spend the time exploring what you can?

Enter the Empty House, now the Kennel Club.

Go right to the adjacent room and look down.

See the TRAPDOOR? (You might have noticed this empty earlier.)

Use your CROWBAR on it.

You can now take the ALIEN POWER SOURCE, just like Mr. Gordon said.

There's one more thing to do here.

Aren't you curious to know what is going on behind closed doors in that so-called Kennel Club?

There is a way to find out.

You'll just have to be sneaky.

Since you can't get past the locked doors, try and find another way to peek in.

See the balcony?

Do you think you can climb up there?

Tools used for climbing down can also be used for climbing up.

Tug at the ROPE hanging from the rock wall next to the Welcome Sign to get back your mop-rope contraption, if you haven't done so already.

Use it on the BALCONY of the Kennel Club.

Climb up and peek through the SHUTTERS by tapping them.

Climb back down to find the dogs have now conveniently wandered off.
