-
advantages of spaying/neutering dogs early
dec separation anxiety, escaping behavior
-
disadvantages to spaying too early
- cystitis
- incontinence
- inc hip dysplasia (males also)
-
safe age to spay puppy
3 mth
-
why spay/neuter at early age?
- eliminate mammary neoplasia
- eliminate unwanted litters
- eliminate pyometra
- eliminate prostatic hyperplasia
- dec aggression
- dec aggression and territoriality
- faster recovery
- easier for doctor
-
non-preventable complications during spay
- estrogen responsive eunuchoid syndrome
- obesity
- suture rxn
-
pregnant uterus removal
- more vascular and friable
- great blood/fluid loss
- individual ligatiion of uterine aa and vv
- milk fetus cranially before clamping
-
scrotal ablation
- bc neoplasia, trauma, pendulous
- don't remove too much
- be cautious of lacerationg underlying spermatic cord
-
pyometra
- pus filled uterus
- mild, chronic problem to acute and life threatening
- dz of diestrus
- need ovarian or exogenous PG
- E. coli
- closed cervix- always sx, more clinical signs
- pre and post op care very important
- friable uterus
- ligatures placed in cervix
- lavage
- samples for culture
-
cesarian section
- dystocia
- dam exhausted
- lift horns out
- milk puppies/kittens thru incision
- genlty pull out placenta
- if keeping uterus then double ligate- cushing then Lmebert
- omentum tacked over uterine incision
-
cryptorchid
- faillure of testes to descend
- can become neoplastic
- always remove both
- intra-abdominal
-
