We have a newly-adopted puppy (5 months old, Border Collie X Kelpie; lovely, desexed, vaccinated, microchipped, in great healthy condition etc.) & I bought a Seresto Tick and Flea Collar (for ~$50 from memory, from local pet store @ their recommendation).Whilst our property has no fleas, the adjacent bushland etc. certainly has ticks – so far puppy seems fine, no evidence of any fleas nor ticks during regular checks; though she does occasionally scratch herself a little around the neck.On our previous dog I used to use frontline (monthly I think?), then later changed to Preventic collars (then similar Killtix collars), as well as some periods of Nexguard monthly chews, from memory...Which basically worked OK.1st time using Seresto collar – do they seem quite good, to all who use them?
