Dog birth control

Thursday March 31st, 2011

Question:

I've heard about birth control pills and implants for dogs. Are these safe alternatives to spaying and neutering?

Answer:

For most pet owners, spaying or neutering--the 100% effective method of preventing unwanted puppies--still by far makes the most sense if you don't plan to breed your dog.

That said, there are alternatives out there. A removable implant called Suprelorin stops testosterone and sperm production for months at a time in male dogs, and it doesn't require the removal of the testicles. Though the implant is not yet available in the U.S., measures for approval are underway. Neutering, however, is still the less expensive option if you're looking for long-term protection.

For females, oral contraceptives are available. Depending on the type (liquid vs. tablet) the dose is either given 30 days in a row prior to your female dog's heat cycle or at the beginning of the heat cycle to delay the onset.

One issue with this option is that since heat cycles vary, it's not always possible to predict the correct starting date. Another issue is the long list of possible unwanted side effects:

Infertility
Liver damage
Vaginal infections
Urinary accidents in the house
Body odor
Skin problems
Mounting other dogs
Behavioral changes
Uterus infection
Mammary gland cancer and/or enlargement
Weight gain
Skin and coat changes

As with any major health decisions you make for your pet, be sure to discuss all options--and all the risks--with your veterinarian.

help please!
i have a 5 year old male staffordshire bull terrier. he has not been neutered and up until recently we have never had a problem with other dogs. bitches he is fine with, but on two occasions he has shown dominance towards another dog with has led to him becoming aggressive towards them. we are responsible, we keep him on a lead and if need be let a fellow dog owner know he is not very good with them. however if another dog off leash approaches him he goes into fight mode and recently a stray akita ran towards him and my dog flipped it over and grabbed a mouth full of fur. my dog will not get the exercise he needs kept on a leash and i do not wish for him to wear a muzzle. will neutering my dog eliviate the problem? we do not stud him and we have only had him for 18 months but because his temperament has always been brilliant, especially with our children we never felt the need.
Neuter
My dog is an Australian Shepard and Blue Heeler he is approx. 8 years old he is not neutered we had no problems until we moved to the country and there is all sorts of dogs running loose. Now my dog is acting like he wants to run with the dogs and whines all the time I thought it was because his brother passed away about a month ago but now I am thinking it is because he is not neutered. Can someone give me some insite on this? Will it be safe to have the surgery done with him being 8 Years old? I would call my vet but it is saturday night.
My lil man after neutering
I had my male dog neutered about 2 wks ago. I also have a female who is in heat now. The male dog is acting 10 times worse than he ever has, not eating, and when he does, throwing it back up and whining all the time. Is there anything I can do? He is driving me nuts.
Neutering my Cocker Spaniel
We have a wonderful, playful sweet Cocker Spaniel who will be three years old on St. Patricks Day. Around Thanksgiving we took him and our 11 year old Cocker to the groomer. That's when the problem began. Murphy, 11, is neutered and was crazy before he was. However, Riley was never agressive, peeing or humping until he came from the groomers. He was bothering Murphy for two weeks at which time we separated the two. Now Rileys at it again. I don't want to change his wonderful personality but I cannot put up with this behavior. Do you think he will change from his sweet playful self to a lazy, slow moving cocker, devil may care dog? We love both our dogs so much, but can't supervise this behavior all the time. Murphy has always been grumpy but Riley is the life of the party. Please help me !!!
