We made Imli wear a collar for the first time yesterday and she keeps scratching her neck. Is this just part of her adjusting to the collar?

Hello Sanchit. Make sure the collar isn't too tight for your pet. May be she is allergic to this product, if that's a case you can switch to collars made out of cotton material. Secondly, check if there are any lesions beneath the collar to rule out any sort of infection.
