Urgh. Help me make a decision, here please... We usually use the Small/Medium Scalibor collar.
Scalibor collars come in 2 sizes (Small/Medium and Large).
The Small/Medium has 4% deltamethrin which is 0.76 deltamethrin per collar.
The Large is also 4% deltamethrin which is 1g deltamethrin per collar. So - there's more collar (it's longer), so more deltamethrin.
So the problem is... Due to Brexit, the Small/Medium collar isn't available almost anywhere except with a use-by date of June 2021. Apparently (according to manufacturer) this means it has to be started to be used before June, not finish its 6 months by then. Now, we may not go away before then. Or we may. It depends on Covid and travel. I also find that old Scalibor collars get very powdery with the white stuff on them, which being a pesticide kinda worries me....
Also, Scalibor collars just say to trim any excess length off. So if I get the Large one (no expiry date issues), can't I just trim it down when I put it on? It's not going to give more of the drug because the % is the same and the length of the collar is proportionate to the size of the dog's neck, whatever size is used? They are both 4% of whatever length they are, and we're trimming it to fit the dog...
Do I:
Use the Small/Medium collars with expiry date of June 2021?
Use the Large collar and just trim it down?
Use another product, probably the Seresto? (I've not used this before and it has 2 meds in it - imidaclopramid and flumethrin, for fleas and ticks - rather than just the deltamethrin for ticks, which the Scalibor has. We don't really need to treat for fleas...and I try to only use meds for what I need).
Answers please, I need to stop procrastinating on this one!!!
