Do you neuter heartworm positive dogs have a rescue had him about 7 months now he is a pitbull about 2 yo.he was so emaciated when we found him recently is showing aggression towards myself and husband and my other dogs

I am gonna address the heartworm definitely but now that he is healthy .

It's more important to address the heartworms maybe his aggression is because he's in a lot of pain

I would take him or she to a vet, they are equipped to handle this situation.

Yes

They do neuter but I would call about treating the heartworm.
