I have a national diploma in animal care for which I studied at College Of West Anglia for 2 years. Some of the things I studied were animal training, first aid, husbandry and enrichment techniques.
Since I was born I've had dogs around me, ranging from the size of a small playful westie to a large stubborn Akita so size is no issue.
I believe its important to make your dog feel like my home is their home so there is no restrictions in regards to where they can lay or sleep in the house.
My home is a Ground Floor flat with its own garden. The garden itself is quite small however there is a huge green/ park 10 meters from my front door. I have a big living/ dining area, two large bedrooms. Its only myself and my 6 year old daughter living there. No other pets.
I must add I have recently started full time work, Mon-Fri 9-5 so I can no longer offer day care or walking services. For those boarding at mine I go home during my lunch break to walk but I would only advise that pooches that are familiar to this routine would come and stay.
