Answer:39 chromosomes

Explanation; meiosis is a form of nuclear division that produces gametes with half the number of chromosomes in the parent cell.it involves two successive divisions to produce four daughter cells.meiosis occurs only in reproductive cells.

In this case,the dog has 39 pairs of chromosomes,which is 78 chromosomes.it would undergo meiotic division to produce the half number of chromosomes,which is 39 chromosomes.this 39 haploid chromosomes are contained in the sperm cells or in the egg cells.

When the egg and sperm fuses,the diploid number of chromosomes is restored.
