We have a 6 mnth old puppy who is very dominant. She's a biter,but I've found that saying "be gentle"makes her a little softer using her teeth. She now sometimes is playing with a toy and all of a sudden she'll pin her ears right back ,and take a lunge at you,preferably at your face. Her eyes are fierce and she really is annoyed at something.We've managed to avoid being bitten by her,but I don't find this behaviour in anyway normal. She's our fourth boxer,but our first bitch ( we were told to buy a bitch as they were nice and calm,better for the older citizens). She's proved that theorie to be wrong. Her trainer finds her very hard to handle ,and keeps advising us to use a hard hand,the harder you treat her,the more vicious she gets,so I'm using the more gentle approach and I feel that she's calmer. She's just had another lunge at me this evening( usually it's my husband who gets the rough treatment). We are expecting our first grandchild in august and there's no way I can let this dog anywhere near a baby as we can't trust her. The squirt bottle is no use,as she loves drinking the water. Please Help,I don't want to be defeated by a puppy. :( Paula.
