dogs, dogs, and more dogs

Hey all, just had a very enthusiastic applicant apply with 8 dogs!! Have not received the applicant screening back yet. They were curious to see if I would lower the pet fee or allow them to pay it over time. The pet fee is $300 each pet. Would it be a mistake to rent to people with a herd of canines or lower the fee? $2400 plus rent and deposit is a hefty price to pay.

Thanks,
