Q

Palpation

A

Can be inconclusive

25 to 40 days after conception; gentle abdominal palpation of chorionic vesicles

40 days to term; general caudal abdominal distention but no distinct puppy bumps (cohesive enlargement)

50 days to term (late gestation) may actually palpate individual fetuses

Q

Weight

A

Conception greatest for females with BCS below ideal weight

Overweight females have increased problems during pregnancy and higher chance of dystocia

Q

Nutrition: What to feed

A

NRC and AAFCO approved diet formulated for all life stages

Carbohydrates, protein, fat at proper proportion
Vitamins, minerals, aa

Do NOT provide extra calcium supplementation during pregnancy; can/will cause Hypocalcemia (dogs do not draw Ca from diet but from Ca stores)

Q

Nutrition: How much to feed

A

Feed the same as done prior to pregnancy and increase only at 3 weeks prior to whelping (when energy demand increases significantly)

Increase fed gradually over 7, 8, and 9 weeks to 50% pre-breeding intake

Lactation: increase fed up to 3 times the pre-breeding by third week of lactation

Q

When is fetal growth rate the greatest?

A

Last 3 weeks of the pregnancy

Female will increase BW by 25% during this time

22
Q

Pregnancy disorders relating to diet and energy (4)

A

Puerperal tetany/Eclampsia
Hypoglycemia
Pregnancy toxemia
Gestational diabetes mellitus

23
Q

Puerperal Tetany/Eclampsia/Hypocalcemia
When?
What occurs?

A

Occurs most frequently at highest lactation

Loss of membrane bound calcium allows easier depolarization of muscle fibers

24
Q

Puerperal Tetany/Eclampsia/Hypocalcemia

Clinical Signs

A
Uterine inertia
Panting
Whining
Muscle fasciculations
Seizures
Hyperthermia
25
Q

Puerperal Tetany/Eclampsia/Hypocalcemia

Bloodwork Abdnormalities

A

Hypocalcemia with normal albumin

26
Q

Puerperal Tetany/Eclampsia/Hypocalcemia

Treatment

A

Acute: administer calcium slowly via IV

Monitor heart rate; stop injection with dysrhythmia

Oral supplementation with calcium carbonate and Vitamin D

27
Q

Hypoglycemia

A

Uncommon

Clinical signs similar to puerperal tetany

Treat with IV dextrose

Check for glucosuria; R/O diabetes

28
Q

Pregnancy Toxemia

Cause

A

Uncommon in dogs

Life threatening for pups and mom; may have to terminate pregnancy

Cause:
Large litter size and inadequate nutrition -> ketosis (must differentiate from diabetes mellitus)
Anorexia during the last 2-3 weeks of pregnancy

29
Q

Gestational diabetes mellitus

How?

A

Progesterone stimulates growth hormone and leads to insulin resistance during late pregnancy

Could see DKA

30
Q

Gestational diabetes mellitus

Diagnosis

A

High serum glucose or high urine glucose and urine ketones

Insulin therapy may help early in the disease

31
Q

Drug administration consideration

A

Puppy effects

Pregnancy associated changes in serum albumin, CO, renal clearance

Q
