Hi Pat,
TRD can be difficult, but not when you know how to deal with them..
The dogs general temperament and how you raise them is a big factor.
Having 1 is easy, but when you throw a few into the mix, it can be challenging.
How you train them, the quality of time and activity you giev them and the constant challenge of their mind puts them in a balanced mindset.
Some just cant grasp this and expect a dog to be a dog and in their eyes, this means a licky, slobby couch potatoe that wont hurt anyone or anything.
They can surely be that but they can also be the exact opposite.
