Nop. It has a different meaning. Procurar = look for. Pesquisar = search, examine. If you that it seems like they will do some researches on the dog, like through a sirgury and then use its organs, or to study about its species
procurar por = look for. procurar para = look for something TO someone. (I'm looking for the dog = estou procurando pelo (por+o) cachorro. Estou procurando uma coleira (leash) para meu cachorro). Got it?
