The Weimaraner dog breed has a difficult, but generally good character and is very loyal to its owner and family. However, there is also a downside to the coin. If the dog is left to itself, not to engage in its upbringing and socialization, the instincts that it carries in itself from nature will prevail. It’s unavoidable. You must understand that this is, nevertheless, an animal.
#1 Please note that the Weimaraner will dig under the fence

#2 gnaw at furniture

#3 exterminate cats and all small animals in general, except perhaps for small dogs (although here there is no complete certainty)

My Weim rarely barks but I agree with most of this.
