 The Weakening Blow ability is excellent to use for capturing pets when pet battling since the pet does not get killed by the attack.

 

Note: if the weather effect during the battle is lightning, the enemy mob can still be killed by the lightning strike!

If you do not have any of the pets with Weakening Blow, there are some alternatives:

 

Corgi Pup

Corgnelius

Grumpy

Molten Corgi

Scraps

 

They all have Superbark which is the exact same power.
