Is this harness good for a dog that pulls?

Yes, that is its main strength. The front D-ring lets you clip the leash at the chest so a pull turns the dog sideways, and the wide vest panel spreads pressure instead of digging into the throat.

How do I choose the right size?

Measure the chest girth just behind the front legs and the neck, then compare with the size chart. Sizing runs inconsistent, so if a measurement falls between two sizes, size up and use the straps to tighten.

Is it suitable for small dogs?

Usually not. The vest is bulky and stiff, and the padding and fabric add weight that small breeds notice. It suits medium to large dogs better.

Can I use it in hot weather?

It is a poor choice for heat. The thick fabric and padding trap warmth, so it is better for cool and mild weather or shaded walks.

Does it have a handle for lifting the dog?

Most versions include a top grab handle, which helps lift a dog over obstacles or hold it steady during training. Check the specific listing, since some variants omit it.
