PEARLS & CONSIDERATIONS
Comments
• Animals should be tested for brucellosis and
heritable disorders before breeding.
• Semen quality should be assessed in advance
of insemination.
• In-house test kits for semiquantitative
determination of serum progesterone and
LH concentrations of bitches are available
for use when veterinary diagnostic laboratory
services are not available.
Technician Tips

cornerstone of success.
Client Education
• Days 3-8 or days 4 and 6 after the LH surge
are the most fertile days for breeding bitches,
but pregnancies can result from breeding up
to 3 days earlier or 2 days later using fresh
semen.
• Estrus monitoring is also used to predict the
most likely whelping date: 65 (± 1) days
after the LH surge or 57 (± 2) days after
cytologic diestrus (D1).
