early neutering (8-16 weeks)
 
i am totally for spaying and neutering pets.
my question about doing this early is; can this stunt their growth / maturity?
my cat Ichabod (male) was neutered young. when he had a problem with crystals and ended up with a blockage, my vet informed me that he had a very small penis. which made the blockage difficult to treat. i'm just wondering if the early neuter might have anything to do with this???
thoughts?

Hi there ichabod'smom,

As far as i know early spays and neuters don't have anything to do with the size of the penis. I'd be curious to know if other members agree though.

here's a general podcast we recorded a few years ago that might be of interest.

thanks. i did listen to the pod cast. there was nothing in it about size....

Research I've read disagrees. Mostly I've read the dog literature but some of it covered dogs and cats. Some said such extremely early neuter as paediatric might indeed result in smaller growth of penis and especially in cats where the ureter is small anyway it could cause problems if there was a blockage. Other readings said no. I can point you to a list of information on neuter/spay considerations in cats....umm wait, I think I do have one that deals more with cats. Wait while I go look at the Kustritz research....

[QUOTE]Feline lower urinary tract disease is a syndrome
consisting of hematuria, dysuria or pollakiuria, and possible
urethral obstruction and is most commonly classified
as idiopathic. The reported incidence of FLUTD
is 0.6%.134 Despite numerous vehemently declared
anecdotes of an increase in the incidence of urethral
obstruction in male cats castrated when young, numerous
studies35,132,135 have failed to detect a correlation between
gonadectomy of cats at any age and a decrease
in diameter of the urethra or an increase in incidence
of FLUTD, with or without urethral obstruction. In 1
large study,136 investigators identified gonadectomy as
a risk factor for development of FLUTD in both female
and male cats and also identified an increased risk of
development of FLUTD in overweight or obese cats. In
that study, sexually intact female cats had a relatively
reduced risk for development of FLUTD.[/QUOTE]

As you can see this one says no. But I have read others that said yes. I think how you define "young" is important. Young might mean pre-puberty for some but I'm thinking you mean paediatric which varies but might be before 12 weeks or even before 8 weeks?

i have hear that spaying or neutering the pet early can cause the animal not to grow as big as they should have,. other say it doesn't effect the animal at all. So i guess it all depends on the animal.

That can put joint angles out and the fact there are more orthopedic problems in such dogs than in intact dogs is thus believed by many to be related to pre-puberty neuter/spay.

A male dog neutered before puberty may not develop in his head, neck and shoulders and be smaller there than an intact male. This effect is not so noticeable in the girls who don't bulk up in those areas like the boys do anyway. This is quite easily seen in horses. A gelding cut early will not have the neck muscles of a stallion.

rottysrule, this would be of concern in your breed, a large breed dog. I have provided a list of readings, all scientific research before on this board. If you can't find it I can post it again. Certainly there are far more reasons than mere appearance and more health concerns than just the joint one to neuter spay pre-puberty or even at all, as more recent research is beginning to show.

I don't have any information on spay/neuter in cats that young, but it does seem extreme to me. The animals have these organs for a reason, and removing them that early has got to have an effect.

I did notice that my last dog china wasn't as big as she should have been and we got her fixed around her first heat.. my dog Nyx who a rotty mix just got fixed just before 2 and i have a pitty mix who got also fixed this past month and she was under a year. only reason we got both done right away is there was an intact male that got would get out and it was driving me nuts as i was afraid to let my dogs out in my fenced back yard in the off chance he got in my yard. My next dog(years down the line) probably wont be fixed until 2 also , as i want the pup to grow the way it should.

I'm not sure I made it clear. A dog/bitch neutered pre-puberty may grow TALLER than nature intended. Ultimate weight is not believed to be affected. A male neutered pre-puberty may be Smaller in his head, neck and shoulders and chest than nature intended.

If the dog is not purebred then you can't even guess what the final outcome should have been. Even within same sex litters of purebreds of known parentage final growth can vary.
