advice

Hey all.
Do pups go through a sorta lapse in behaviour at about 5 and a half months?
We have been doin so well with her but this week has been very testing she is very challenging as in will bark in my face! And after her little teeth coming out she is now biting again and when you say no she does it anyway, also walking on lead she has decided shes not listening to me and has been swinging off the lead snarling again! Also in house shes in at everything.
Just so wierd as things have been goin great

Just be firm with her, they do go through stages were they can test the boundaries, be patient & persistent and she'll settle down again

Yes, she's not a little baby any more and is practising to becoming a teenager! She's pushing it to see how far she can get - all puppies (like little humans) will do this.

Just stay calm and consistent with your training and you'll get there!

Can only echo the advise above, Rocky did the same quite a few times, stay firm and keep going with your normal training, she will eventually figure out she cant get what she wants!

Thanks guys
Iv never had a dog quite like her lol, shes crazy....when she has mental moments of running round the living room at 60mph she flings herself beside my mum or me and just stops! Shes also extreeeeeemly vocal.
Will just keep doing what we r doing
Anyone any tips for walking better on lead??? Its the 1 thing at class she just wont do and she pulls awful all of a sudden shes so excited by everything

Yes defo testing how far she can push you, typical teenager!
And yes they do have their loony moments:) 

All sounds very normal!

Do you use a harness when walking? I found that walking Moo on a harness really reduced how she pulled Xx
