most good vets these day will let you pay weekly. a good vet dosent care to much about the money they just care about the pet and if your not in work get down to the pdsa all they ask for is a donation.
IMHO thats all vets want is your fecking money. i get a tin of blue spray from a farmer what they use on cattle god knows what its called but it heals my dogs wounds with a weeek or so. jon
