Sounds like you've got a submissive pee'er there. Been there, done that.........L
OL. Dont' want to do it again.
Yes, he should probably outgrow it. There are some things you can do though to keep him from feeling so insecure.
When disciplining him, try not to raise your voice too much, not more than a decible or two.........lo
l. The louder you are, the more likely he will pee, especially if you are looking at him and near him.
Also when disciplining..
.....try not to get down in his face, or lean down over him. This will make him feel threatened or insecure, and he will pee.
Praise, praise, and praise some more for proper behavior. this will boost his confidence and confident pups don't pee submissively.
When he's in trouble, I suggest giving him time outs. Correct him and tell him "NO" or whatever, but when putting him in time out do so as calmly as you can.
Keiko was a submissive pee'er off and on until she was about 5 or 6 mo old. I worked very hard to be a "gentle" disciplinarian
.......lol....
....so she wouldn't turn out to be a submissive adult. Build confidence in the dog and he will outgrow it. If he is feeling constantly threatened or afraid he may never get over it, and could eventually become fear aggressive.
Good luck!
