Use these lines of command on a pet macro if you have one

/stopmacro [target=pet, nodead]
/run PetDismiss()

It will dismiss your pet only if it is dead, so you can cast a new one right away, without rightclicking the pet portrait.
My full pet summon and freeze macro looks like this.

#showtooltip Summon Water Elemental
/cast [nopet]Summon Water Elemental; Freeze
/stopmacro [target=pet, nodead]
/run PetDismiss()
