My 6 month old GSD is getting spayed in 2 days and since she'll have to wear one of those cone things to keep her from chewing at her stitches I thought I better give her a flea bath first. I also have Frontline to put on her but have been told I should wait at least 24 hrs after bathing to put it on. Is this true? In order for that to happen I would have to bathe her tonight. I firgure that I won't be able to bathe her for awhile after her surgery. I have some concerns about giving her a bath at night. Is it a big deal? I just don't know which is worse a bath at night or going to the vet for surgery being dirty?
