It depends to your dog if your dog look ative again as he is in normal he can swim :)
One month after you used the last flea & tick treatment, unless you can see it is not working then go ahead and use the Frontline.
i think its an hour
2-3 months
It is usually recommended you wait at least a week.
3 months.
well it depends on the swim team if they are like mine we wait a couple of days after our first meeting. but if your like the other guys you wait a long time and don't win the meet
I would suggest that you wait until the end of your swim season and do it the day that season ends. I swim and got mine done in the beginning of my season, for the rest of it I could not wear my cap over that ear.
half an hour
On a human you wait it out and the will disappear
You don't need to wait -your filter system will feed it in gradually and it will spread through the water.
Read and follow the product label for instructions from the manufacturer of the product!!!!
It really doesn't matter how long you wait because chlorine is bad no matter how long you wait. It helps a little if you wet your hair with fresh water before swimming, also put a leave-in conditioner on before you swim, this way your hair won't absorb as much chlorine.
