A recently neutered male dog may potentially impregnate a receptive female for as long as one month after surgery. Sperm is produced in the testicles then mixes with seminal fluid in the prostate. It is possible for those sperm to survive for as long as a month after the testes, which replenish the supply, are removed. Additionally, testosterone levels are still high in the male and he will want mate with a receptive female until those levels decline.
