At a rate of 30 minutes per poodle, 3 poodles will take 3*30=<<3*30=90>>90 minutes.

If it takes half as much time to groom a terrier as it takes to groom a poodle, it takes 30/2=<<30/2=15>>15 minutes per terrier.

At a rate of 15 minutes per terrier, 8 terriers will take 120 minutes.

Thus, in total, it will take the pet shop 90+120=<<90+120=210>>210 minutes to groom 3 poodles and 8 terriers.
