I know this is going to sound crazy but I wanted to get your opinion. When we got Daisy, the breeder told us not to put her on heartworm medication because Bassets have bad reactions to it. I asked my vet and he just laughed it off and basically said the breeder didn't know what they were talking about. Daisy is almost four months old and will be going in and starting heartworm meds. have any of you heard that Bassets shouldn't be on them?
