little ovoid one

J.: Labradoodles require a lot of energy. Over the weekend, he likes to walk ten miles a day.
A.: I wish Gracie liked to walk. The first thing I'll do in the new house is build the rest of the gate, so she can play in the yard.
U.: Won't she be able to slide under or through the gate?
J.: She's kind of big.
A.: Yeah, that's a good point. She is big.

Later, I showed U. a picture of Gracie.

U.: I don't think she'll be slipping through under the gate.
