VTHT 2201 Canine and Feline Clinical Management Canine Reproduction Canine Estrous Cycle 4 stages Proestrus – attracts male but won’t mate; blood-tinged vaginal discharge; vulva moderately enlarged Estrus – serous, straw-colored discharge; vulva at peak swelling; accepts male; breed every other day for one week Diestrus – mucoid vaginal discharge that diminishes; +/- pregnancy; swelling of vulva resolves; won’t accept male; whelping occurs 57-58 days after onset Anestrus – no outwardly apparent signs of heat; male shows no interest; uterus repairing Educating Clients About The Canine Estrous Cycle First two stages referred to as “in heat” or “in season” Client questions How do I know when she’s in heat? When should I breed her? When will she deliver the pups? Clinical observations and diagnostic tests provide info to answer these questions Canine Breeding Female should be over 18 months old; usually breed on the 2nd or 3rd heat cycle Stud dog should be over 18 months old Both dogs should be current on vaccinations, HW preventative and parasite control Male and female should have brucellosis test prior to breeding (Brucella canis) Venereal disease Bacterial infection Rapid Slide Agglutination Test – very sensitive test; almost never have false negatives, but may produce false positives; positive tests should be confirmed with different test Canine Breeding Methods Natural Breeding Bring female to stud dog Breed every other day once she is in estrus OR breed on days 3- 6/7 after Luteinizing Hormone surge (hormone testing must be done) “Tie” can last 2-30 minutes; usually about 15 Do NOT attempt to separate caused by swelling of bulbis glandis Artificial Insemination Fresh cooled semen MUST use hormone testing, inseminate 3-6/7 days after L.H. surge Canine Pregnancy Facts Lasts 63 days after ovulation 57-58 days from onset of diestrus Pregnancy detection Palpate amniotic sacs in uterus from around 25 to 35 days gestation ultrasound after 21 days gestation radiographs after 6-7 weeks gestation, can count puppies blood test, relaxin, after 3-4 weeks gestation Canine Healthcare During Pregnancy Continue HW prev. and flea control No MLV vaccines Puppy food starting at 4 weeks gestation Deworming? Which common parasite may be transmitted across the placenta? Canine roundworms Which common parasites may be transmitted through milk? Canine roundworms and hookworms Are these parasites zoonotic? YES! Parasite Control for Mom and Pups Fenbendazole- treat female daily from day 40 of gestation until pups are 2 weeks old Ivermectin- treat female on days 0, 30 and 60 of gestation, and again when pups are 10 days old (NEVER use high doses of ivermectin in herding breeds) Treating puppies Pyrantel Pamoate (Nemex, Strongid T) 2, 4, 6, and 8 weeks Treat the dam right after the pups are born, then treat along with the pups
