Hi
When I bought my TT he cost £450 over 2 years ago. Now the prices are more like £500-£650 plus.
If you are looking for a puppy as I have for the last year please ensure the parents have had the relevant health checks (hipscored & clear eye certs).
I am quite a new dog owner & I'm sure someone more experienced will be along to help you if you need anymore help on the breed, when I was looking initially I contacted the breed club who were very helpful & I bought books on the breed which also helped.
