Insect repellent for dogs random I know

[underseige05]

My 18month old sprollie loves her walks and we often if not every other day walk her through the field at the end of our road. We dont usually have any issue's but since the grass has got longer and the fact she loves to jump through it, we noticed tonight that she is covered in bites on her belly. They look identical to the ones my DH has all over his legs from insect bites he got from the field 2 nights ago.
They arent bothering her I dont think at the moment, but she loves this field as it has clean water that she can swim in so dont want to stop going through the summer.
So was wondering if anyone can reccomend a spray we could use as the internet is bringing up so many Im unsure where to start.
I will obviously be taking her the vets if they begin to bother her or if they get infected etc

If the red areas aren't bothering her I would let well alone. Any spray is going to introduce unwanted chemicals to your clean water too, which might be harmful to aquatic life.

It could also be allergies rather than bites. Quite a lot of dog have allergies to grass and clover.

Spray never used it but you can get this
