I'm a bit rusty but I used to have Amstaffs, just in between at the moment, I did show, do obedience and bred one litter some years ago so maybe some stuff in the memory bank might be useful here...
1. What is my relationship with the breed? (ie breeder, first time owner etc)
I was a breeder if one litter counts and have had two AmStaffs so far and loved them and the breed to bits, still grieving their losses. I have other family dogs, cats and horses so I need to wait till there is room and time for another AmStaff.
2. Where and why was the breed first developed?
Memory tells me that the breed was first recognised in America around 1934/35 when there was a split between those wanting to name them American Staffordshire Terriers and those whose preference was the American Pit Bull Terrier, and that is where the two breeds first began to be separated, (including different kennel clubs recognising teach breed, UKC & AKC I think) The split occurred however, in the 70's I think it was, AmStaffs were used to 'add fresh lines' to the APBT and there are still dual registered dogs today. The breed was first developed from bully type breeds, the White Bull Terrier rings a bell, and a few other 'english' breeds and used as 'butchers dogs' they were required to hold the bull by the muzzle so that the butcher could do his job. They went on to become family guardians, herding dogs and generally held any role their owner required. Or so the books tell me if I have remembered correctly...
3. How common is it in Australia?
These days the AmStaff can be found for sale in too many papers and too many pounds and shelters seem to have them up for adoption, or at least they are listed as AmStaffs and crosses.
4. What is the average lifespan?
12 to 14 years.
5. What is the general temperament/personality?
Very much like the staffy bull terriers - they love their family, they love to please their owners (if they understand what you want) and are typical boisterous terriers who have strong jaws and can chew through lots of shoes if bored :)
6. How much daily exercise is needed for the average adult?
Regular daily walking, playing, running and toys definitely and mental stimulation is very important, however, having said that, my first girl didn't hold weight well so she didn't require as much walking and didn't seem to miss it.
7. Is it a breed that a first time dog owner could easily cope with?
Provided they have commonsense and intend to put the effort into understanding what an energetic and intelligent dog they have and that they research the breed to be sure they can devote the time, socialisation and training into their dog to end up with a fantastic friend, but most dogs need owners who have commonsense and time don't they?
8. Can solo dogs of this breed easily occupy themselves for long periods?
I think it really depends on the dog, some can be incredibly full on needing time, attention, training and even a doggy playmate and others are happy to lay in the warm sun while you are at work etc.
9. How much grooming is required?
Minimal, the occasional brush if you feel like it, although a good rub/massage is probably as good, and a bath when they need one.
10. Is it too boisterous for very small children or for infirm people (unless the dog is well trained)?
Some can be, this is an incredibly strong dog in a fairly smalll package, or at least it's a small package if it's close to the preferred heights for the breed so if they are not well trained then yeah, they can be boisterous, they are terriers after all. An adult dog may be less boisterous than a pup or juvenile, but they are for the most part easily trained. I hear and read stories of them having an innate sense of who they need to be gentle with, and I know my girls were calmer than usual when around my new born son but maybe they had simply matured and calmed and it was just coincidence.
11. Are there any common hereditary problems a puppy buyer should be aware of?
Ataxia was not not around when I was more seriously involved (early 90's) so I don't know much about it.
Hip displaysia can be an issue, I wonder if it's because the dogs are getting heavier and too solid, I don't know but it wasn't as common back then in the breed. Elbows can now be an issue, again, I don't recall it being an issue.
I was aware of epilepsy in two related dogs, they weren't closely related so I don't know if hereditary or if an issue these days.
12. When buying a puppy, what are the things you should ask of the breeder? (eg what health tests have been done (if applicable) and what is an acceptable result to those tests so the buyer has an idea of what the result should be)
Dependent on why you are buying an AmStaff, you need to know their history with the breed, what papers the pup will have, are pups ataxia clear by parentage and the parents too, any history of any health issues, hips, elbows, anything. Agression in any of the lines, what are they breeding for, in particular with AmStaffs as some breeders are breeding for size "big heads, big boned" but there is only one breed standard and this is not what the standard is aiming for, a big oversized, dog can't perform to the same standard as a less heavy, fitter dog when asked to work whether as a butchers dog or as a herding animal etc. Making sure the pups nose, lips and eyelids colour in black or very dark grey/blue is important and espcially these days with BSL, AmStaffs shouldn't have a red nose, although very occasionally, they will which possibly links back to colour dilutions, or, dual registrations back in the lines. If going for a show ring or future breeding stock pup then of course you need to know your standard, make sure the lines don't carry the obvious defaults like more than 80% white, tri colour, black with tan etc or the hereditary health concerns.
Also, be sure to find out the reputation of the breeder, ask others, ask them what their guarantees are etc. I would hope that all good breeders back their dogs on common sense matters (eg a hereditray issue over a new owner not teaching their dog basic obedience) and would want first option if a dog needed to be rehomed, I know I did.
Whew, I don't know if I actually added anything new or useful but it was fun trying to see what I could remember ;)
