Hi all, we have had a 13 week old jack russell puppy for about 6 weeks now. She has been crate trained since 8 weeks old and is very happy in there at night and during the day when we pop out. My problem is that when i see my 3 children (12,9 & 6 yrs old) she constantly will not leave them alone, she is always jumping up at them and occasionally tears thier clothing with her teeth. We all try to be firm with her and say NO but she doesnt listen. The kids are not winding her up, and i dont believe she is nasty with them just too excitable. I know my kids arent with her 24/7 but i wished she could get used to them more. I said to my partner that we should try to crate her for a little while until she learns to calm down, but my partner disagrees with this and says that she should 'just learn to get used to them' Any advice would be greatly appreciated..
