DH wants to rehome puppy!

[Totallyfloaty35]

We have had our Lab for 6wks and my goodness is he hard work.He eats/chews everything in sight,pees and poos everywhere,even in the crate.He also barks/howls non stop when left alone even for a second.The neighbours have complained and the kids are exhausted from lack of sleep.
He was sleeping in his crate in our room and was great he slept from 11-7.But he is huge and really heavy to carry upstairs(we sleep in attic so its 3 flights) also we needed the crate downstairs for his daytime control.But he howls when we leave him in the kitchen with the Chihuahuas.
DH has had enough and wants him gone.Yesterday the pup jumped at our 3yr old and caught her face with his paw,she now has a slash mark from eye to chin and looks like she has been knifed it was an accident but it was the last straw for DH,i had to send him to the pub to calm down
Any tips would be a great help,i have booked pup in for a claw clipping and have been trying to get hold of a behavourist but she still has not got back to me.I have never had a pup that acted like this before.

Totally - if you're still looking at this, I have a 15-wk old goldie. He knows he's supposed to sit down to greet people, but just can't help himself jumping up a lot of the time, and has also slashed my 3 and 5 yr-old's faces (and mine, but that's not such a big deal). I got some nail clippers from the pet shop and take the points off. He hates it so it's hard to do, but I got the vet to show me to be sure I wasn't hurting him. He's still big and scratchy, but less lacerating.

Ta Roman,we got his clipped at the groomers! He is a million times better with his DAP collar though,much calmer and easier to control.But i will get vet to show me how to do it for future purposes
