Less than a week after giving my dog her first ever dose of Nexgard Spectra (the vet receptionist sold me on it) my healthy 11 year old spaniel came down with severe diarrhoea and vomiting and after 24 hours was rushed to emergency vet hospital and put on IV fluids for 24 hours at great cost to us. Very distressing.
I am convinced that there is something about the combination of the two drugs that stresses the gastrointestinal and nervous system out as it’s being processed through the body.
I’m raising it with our vet as a potential toxin that kicked off my dog’s hospitalization.
Be very very careful when administering this drug!
