With Miss Tallulah I opted for the blood test and the extra fluids. They are optional but optimal and considering we have Bracycephalic doggies that are at much higher risk for complications or death from anesthesia it is not a bad idea if you can afford it. The actual neutering is not that expensive on your estimate, but your vet is being responsible by including those things. But if you don't feel right about your vet trust your instincts. You want someone you can trust and develop a long term relationship with.
