Vet Visits for a sick dog can cost from as low as $50.00 to as high as $300.00 just for the vet visit.
Then if any other medicine or anything else needs done besides a checkup then the cost could go to $200.00 to $500.00
If it's just a routine checkup of your dog then it should be around $50.00 to $150.00 at most but if the dog is sick then it probably needs some other medicine which can vary in costs.
