Hello,
I think that it is best to quell your concerns by seeing your vet. The heartworm should have been resolved with the treatment you were given. But your dog should still be on heartworm preventatives.
I also think that you should follow up with whomever did the surgery for you. It might be post op tracheal inflammation.




He is now throwing up white foam.
Hello,
I apologize for the delay. Im sorry there is not enough information for me to offer any advice other than to seek veterinary help.
I ended up in the vet twice and spent almost $2,000
But he’s doing much better with Miralax and Nordic Natural omega daily
