This is mine and my husband first puppy shes 8 weeks and a chihuaha jack russell mix. We got her monday from a family friend I took her to the vet on tuesday and the poor thing has fleas and roundworms Heres my question i do wash my hands alot after i pick up her accidents and before i eat... but like I have a weak stomach (crohns disease) and my immunity is kinda low when it comes to my stomach. Im kinda on the lookout so i dont get sick from her. They gave her meds and stuff K9 and dewormer and heartguard. and they reassured me Id be okay. But she sat on our couch and stuff... should i spray the couch with like bacterial killer. Maybe im over reacting since shes like 2.5 lbs....and most puppys are born with worms. but i love her and i want to be healthy too. Any advice?
