ok so saturday. i found a white GSD male at our local humane society, and we adopted him. they keep him until hes neutered which was to be done on wednesday, and we could pick him up on thursday. my husband just got a call saying hes heartworm positive, ive had several dog in my life but ive never had to deal with heart worms. i guess im just asking if someone can explain exactly what the treatment is goning to be like and what were gonna have to do... i know its pretty expensive it treat it. and if i need to be worried about my current shepherd, she's on trifexis.
