They are extremely sweet dogs, but in my experience thick as two short planks, and even with consistent lead training and obedience training, they are as another poster mentioned, hard to train to not pull on the lead and train to recall once they have seen a squirrel or source of food .
They shed everywhere, be prepared to have ‘tumbled weeds’ of hair throughout the house and have to hoover regularly. In winter if you are park walking them, you will need to footbath them and dry them off every walk because of their long fur which will get tedious.
The heart problem, even with reputable breeders is an issue and they are very expensive at the vets, with heart murmurs, eye, back, ears and tummy issues.
Very sweet breed, but more trouble than they are worth,
