Hi, I do not use any Heartworm meds or flea meds, I do live Australia & have hot Summers we do get mozzie’s after the rains in Summer but Patch is an indoor dog & doesn’t sleep outdoors, chances of an infected mosquito biting him is very slim, Patches vet hasn’t seen any heartworm cases in my area in 26yrs…she doesn’t seem concerned that Patch isn’t heartworm……Contact your local vets & ask has there been any resent cases of heartworm in your area??…..
