Flashcards in Neutering Deck (11):
1

When should you recommend neutering a bitch?

Over 6 months of age

2

When, in proximity to oestrus, should you spay a bitch?
And why?

AT LEAST 3 months after oestrus
Less vascular and reduces the risk of pseudo pregnancy

3

Why do you get a pseudo pregnancy if you spay a bitch too soon after a season?

Removing the ovary during the luteal phase (when there is a CL) causes a sudden drop in progesterone.
This causes the anterior pituitary to secrete prolactin
= signs of pregnancy

4

What are the emotional effects of a pseudopregnancy?

Fear
Aggression
Vigilance
Anxiety

5

How can you treat a pseudopregnancy that is caused by spaying too early?

Carbergoline (Galastop) = prolactin secretion inhibitor
(NOAH recommends use for 4-6 days, repeat until clinical cure)
Use off license for 14 days to ameliorate the emotional signs

6

What are clinical signs of a pseudopregnancy?

Hyperplasia of the mammary glands
Lactation
Nesting inanimate objects
Anorexia
Fear, anxiety, aggression, vigilance

7

What age should you recommend neutering a dog?

6-12 months
Providing they are not a fear-aggressive, anxious or under-confident dog

8

What are the advantages of neutering?

Removes the risk of testicular tumours
Reduces the risk of BPH (but increases the risk of malignant prostatic cancer)
Decreases testosterone driven behaviours
Eg: humping, scenting, aggression, boisterous, running away

9

When is castration contraindicated?

In nervous aggressive dogs
Can make anxious dogs more anxious

10

When do testosterone driven behaviours develop?

6-9 months

11

What drugs can be used for chemical castration?

Delmadione (Tardak) - progestagen that reduces FSH and LH
Deslorelin (Suprelorin) - desensitises GnRH receptors reduce FSH LH
