About Me
I have been involved in animal rescue, welfare and behavioural research in Europe for more than 20 years.
For me, caring for animals has always been much more than breeding. Over the years, I have worked to create a safe, loving and healthy environment for every animal in my care.
I have interacted with and cared for more than 1,000 animals, learning about their behaviour, personalities and individual needs. This experience has given me a deep understanding of how important patience, trust, socialisation and responsible care are.
I have also taught my children from a young age to respect, protect and love animals, and to understand the responsibility that comes with caring for them.
Animals have always been an important part of our family, and my priority is to make sure every animal receives the care, attention and respect they deserve.
If this is for a puppy advert, I can also make it shorter and more professional so buyers can read it quickly.
