Average Costs. The average costs of a dog DNA test are between $40 and $100. These are the fees charged if the DNA test is performed at a vet clinic. There are also DNA test kits for at home use, which can cost between $35 and $70, but some shipping fees will be extra.
For cats, a blood test +/- urinalysis can range from $80 â $220, while for dogs the cost can be from $90-$250. How often should it be done? Ideally as animals age check-ups should be performed more often.
