I live in Argentina and most flea collars here are not good. However, seresto is being sold here now and I have been told it is good. Is it? It would help a lot with my dog's alergies since it lasts 8 months and nothing would bite him within that time!
I was used seresto for my puppy and I see it really good. Thanks to the collar’s protection span, I have saved a relatively huge amount of money on new flea collar, because compared to other collars that I have tried, Seresto collars’ effect does not seem to wear off quickly. And I like this collar because it doesn't give out any smell from contained repellant chemicals.
I use earth animal internal powder (Yeast free) for my dogs and it’s the best flea and tick product I’ve ever used. Been using it for 2 years and not had a single tick ( I live in the woods). They have flea and tick collars too! I’ve never tried them but I’ve heard great things about the collars as well.
