Good on you Veebs for seeking info before making a call.
My beautiful staffie of 13 years died just over a month ago. She was purebred, registered with papers, bought from a registered breeder as a pup etc. I grew up with the misguided notion that mixed breeds were unpredictable etc, so at the time felt that was the best option. She had good bloodlines, so the breeder talked me into not desexing her to leave options open for a litter one day. The years went past and I never took her down that path. I don't think she was any extra trouble compared to desexed dogs, but she always kept a very lean weight compared to other staffies which was a good thing.
18 months ago her womanly bits became infected and she had to be desexed at 12 years of age to address that issue. Apparently complications with bits that aren't in use can be quite common. In my un-expert opinion, things went downhill very quickly for her since the late desexing - almost instant loss of energy, weight gain, hormonal lumps. From what I now understand, when desexed young before the hormones have kicked in, the body adjusts. When it happens suddenly when old, it's a massive shock to the system. If I had my time again, I would desex as a pup without hesitation. No dramas of being on heat, cheaper registration, no risk of associated health issues and no risk of accidental breeding.
In recent days I have started to look at adopting a new dog. I have been horrified by the euthanasia stats in Australia. I will always adopt homeless dogs from now on. The number of staffies in particular needing homes is FRIGHTENING - even purebred. If interested, check out www.pestrescue.org.au. There are also some interesting euthanasia stats by Council area in NSW at
http://www.savingpets.com.au/nsw-pound-survey-201112/. A bit of Googling pulls up similar stats for other states. Thousands of beautiful healthy happy dogs put to sleep each year because we as a community don't want them.
So I guess my hot tip? Go the snip. Despite your best efforts, your mate may one day slip out of your yard for some action as per the other thread. Better to be safe than even accidentally contribute to a sad problem.
Other sad fact is how quick many Councils are to euthanase with minimal to no effort to locate owners (even when chipped and registered) or rehome. Many stories similar to the other thread - any excuse to euthanase, dogs euthanased within hours of pick up before the owners noticed they were missing etc. Very sad. The good news is, there are some Councils and communities who have really picked up the ball on this issue and are now not euthanasing ANY rehomable dogs. Euthanasia rates down from over 50% to under 10% with only terminally ill or seriously aggressive animals being euthanased.
Lots of sadness in this issue, but lots of hope too. Australians love dogs and our dogs bring us so much joy. We owe it to them to try harder
