Born and raised here, in Ostellato

The puppies are born indoors and stay there for the first month.

Then they move to a pen with the courtyard, among people and everyday noises.

They leave with an ENCI pedigree, microchip and vaccinations.
What they can have learned before leaving, and what not, is explained in what “socialised puppies” means. We do no miracle exercises: on Bio Sensor we have written why the evidence is not there.
How they are born and raisedWhat we do not do
Sometimes a kennel is easier to understand from what it does not do.
The Del Piccolo Diavolo kennel is in Ostellato, in the province of Ferrara, Italy. Here Staffordshire Bull Terrier puppies are born only a few times, leave with the ENCI pedigree after the 60 days required by law, and are collected only from here, where you see the mother. These are the four things we do not do.
We do not have puppies all year round.
One litter, occasionally two, sometimes none. If you write to us at a time when there are none, the answer is that there are none: we do not offer you an acquaintance's puppy and we do not rush you towards a future litter.
We do not ship dogs.
None of our puppies travels by courier: no aircraft holds, no handovers halfway in a car park. Whoever takes a puppy comes to Ostellato. That way they see the mother, the house and the place where it grew up.
We do not treat the pedigree as an accessory.
There is no such thing as a puppy “with” or “without”: the ENCI certificate goes with every dog and is not charged separately.
We do not take offence at questions about the kennel.
On the contrary, they are what tell us who we are dealing with. Whoever asks about the tests, the parents, or what happens if in two years' time they can no longer keep the dog, is the person we would gladly entrust a puppy to.
Who is behind all this, and how one gets from Rottweilers to Staffies: the story is in about us.
How to recognise a breeder who does things properly. Eight criteria and how to check each one, on us as much as on anyone else.
One litter a year, sometimes none
Del Piccolo Diavolo is a Staffordshire Bull Terrier kennel, the Staffy to its enthusiasts, in Ostellato, in the province of Ferrara, Italy, active since 2013. Paolo Boldrini has followed the breed since 2005. He spent eight years studying it before breeding a litter.
How many litters, which tests
We have one litter a year, occasionally two, sometimes none, never on request. All breeding dogs are tested for L2-HGA and HC (HSF4 gene), or clear by parentage with their parents' reports. Our dogs are also clear of degenerative myelopathy (SOD1 gene). The reports are published on the site, with the dog's name and microchip number.
How we choose breeding dogs
We choose breeding dogs on three criteria, in this order: a steady temperament, no hereditary disease and fitting the standard. Temperament comes first because a family takes it home for twelve years. It is also the hardest thing to correct: conformation can be fixed in two or three generations, a fault of character cannot.
At shows
At shows, the dogs bred here have won 1 Italian Champion title and 3 Italian Junior Champion titles, one of them also Slovenian Champion. Then a Junior Champion and Champion of San Marino, and a 4th place at the World Dog Show with Bilquis Goddess Diabhal. In May 2026 Queen of California became Italian Junior Champion. We work with English and Irish bloodlines, mainly Elitebull and Lackyle.
After the placement
Before placing a puppy we want to know the family: a phone call, a few questions, often a visit. And the relationship does not end there. We are available for advice and news even years later. And every dog born here comes back to us, if one day it could no longer stay where it is.
How to check what we write
Every kennel writes that it selects for health. It is a sentence that costs nothing, and indeed everyone writes it. The difference lies in what can be checked without having to believe anyone.
What a Staffordshire Bull Terrier kennel says can be checked in four ways, all from the outside and without asking the breeder anything. The genetic test reports only count if they show the dog's microchip. The pedigrees are on SBTPedigree, the breed's international archive, with grandparents, great-grandparents and littermates (how to read a pedigree explains what to look for). The number of litters a bitch has had is checked in the ENCI studbook, again through the microchip. The show titles are in the public catalogues, with the judge's name. Del Piccolo Diavolo publishes all four, microchip numbers included.
On this site the reports of the breeding dogs are published, not “available on request”. Anyone can download them. Every sheet shows the dog's microchip, the laboratory, the report number and the date.
It is the microchip that makes a report verifiable. Without it, the sheet could be about any dog. With the microchip in plain sight, anyone can compare it with the papers of the dog in front of them, or ask the laboratory to confirm it.
Which tests we do, and what they are
All breeding dogs are tested for L2-HGA and HC (HSF4), or clear by parentage with their parents' reports. Our dogs are also clear of DM-SOD1. The reports, with the microchip number, are published on the dogs' pages.
A neurological disease that usually appears in the first years of life: tremors, unsteady gait, seizures. There is no cure.
Clear: all breeding dogsThe lens of the eye turns cloudy at a young age, often within the first two or three years, leading to blindness.
Clear: all breeding dogsA disease of the spinal cord that appears after eight years of age and slowly leads to paralysis of the hind legs. There is no cure.
Clear: our dogsAll three are recessive diseases. They are found with a DNA test that is done once and lasts a lifetime. Two clear parents cannot have affected puppies. How to read the reports is explained in the genetic testing guide.
What can be checked, and where
The pedigrees. The Del Piccolo Diavolo dogs are registered on SBTPedigree, the breed's international database, with all the dogs and the litters. From there you trace the grandparents, the great-grandparents and the littermates. You see who the dogs behind a name are, and also what is missing.
The pedigree certificates. Every puppy leaves with the ENCI pedigree certificate, which is checked by its studbook number.
The show results. The titles are not self-certified: the show catalogues are public, and the judges who assessed our dogs have a first name and a surname. They are collected in the palmarès.
The dates. Every litter has its date of birth: the most recent in the diary, those of earlier years in the breeding programme. None disappears once the puppies are in their new homes, and that is deliberate: this way anyone can count how many litters we have in a year.
Our females, one by one. Microchip, genetic tests and pedigree: from there you verify ancestry and litters.
Two rules without exceptions
We do not mate two Staffordshire Bull Terriers because they are beautiful. Every mating comes from a reason we can explain: what we are trying to fix and what we are trying to correct. If the answer were "they are two nice dogs", there would be no programme behind it.
We do not place puppies before 60 days, which is a legal requirement and not a choice of ours. For families abroad the timing is longer still, because the rabies vaccination and the official health certificate are needed.
Including what we cannot claim
It also works the other way round. When a puppy is clear by parentage for one disease but not for another, we say so. When for an outside stud we have the report for two conditions and not for four, we say so.
It is the part nobody likes to tell, and it is also the reason the rest stands up: a kennel that only declares the good things is not giving information, it is advertising.
If you are assessing us, or another kennel, the guide on how to recognise a breeder who does things properly lists the eight criteria and how to check them, on us as on anyone else.
How a litter comes about is told in the breeding programme: the choice of the two parents, the weeks in the house, the matching with the family. The history of the litters is there too.
What the judges say about the dogs we breed
These are the results of our Staffies in Italian and international rings. We do not award them: the judges do, and they are written in the public catalogues.
