Hi there,
I don't really know what I'm asking for, other than someone to say that it will all be Ok.
I will try and make a very long story, a little shorter.
I have two yellow labs, a four year old bitch who we had from 8 weeks old and an 16 month old dog who we got last April.
Four year old has always been my baby. Never wee'd in the house (lots of running her outside everytime she ate, woke up etc as a pup), only barks when the doorbell goes and has always been very very well behaved. The younger dog came to us via my sister who knew someone that was looking to rehome him. My sister took him in (when she shouldn't have done as she lives in a rented house, works 12 hours a day and had no free-time to walk him as she's also a single-parent to a 5 year old). So she asked if we would take him.
We took him in, took him to the vets to be castrated and chipped, also needed to have all his vaccinations as they had no records of them being done and found out that he'd had his leg broken badly as a puppy and it was left broken for two weeks because the owners couldn't afford to get it fixed. I'm not saying that they didn't love him at all, they just physically had no way of paying. We then got him insured. A lot of expense, but luckily we had some savings!
We had our DD 10 months before we got the other dog and soon after getting the dog, I was diagnosed with PND. I had started a new job a few months before and was really really struggling.
Several months on and I'm at the end of my tether. I work full-time, have a 19 month old DD and two dogs to look after. I work from home (luckily) so I'm with the dogs all day and the dogs love each other dearly. But I'm really struggling with the younger one. I haven't bonded with him at all and just taking them both out for a walk nearly brings me to tears. We swore when we got him that he would never have another home and that we would never give him up, no matter what he does, but I'm really struggling with it. He wees everytime someone comes into the house (excited spraying - not full-on weeing), eats his own and the other dog's poo so I have to constantly monitor him to make sure that he doesn't lick our DD and he jumps up all the time. (Luckily not at all at DD though - she loves him to bits as does DH).
I work 7am-5pm and then do the teatime/bedtime routine so there is no hope at all of getting him to a training class. I just feel totally overwhelmed and guilty all at the same time. I find that I yell at both of them a lot more than I ever did when it was just the bitch. I would never ever hurt them and always feel guilty when I've yelled but I really am struggling to cope. DH is brilliant and offered to do all the walking aswell as his full-time job and most of the housework. He had been doing all the walking until recently when I decided that I needed the exercise and would feel incredibly guilty going out for a walk WITHOUT taking them with me! But the walks sometimes drive me to tears of frustration as they pull me and trip me up!
Can anyone offer any advice? Even it's just to suggest deep-breathing exercises and to tell me that things will get better as he gets a bit older. Giving him up is not an option, as much as sometimes I wish that it was.
Please help!

PS: Also male dog wakes up at 5am every morning yelping and whining and wakes the baby up, so my day starts at 5am. This is even when DH hasn't come up to bed until midnight so he's only gone 5 hours without a wee!
