When is the right time to get pregnant

[TaraJoy87]

Me and DH have been married 4 years. We have just purchased our first flat, both have decent jobs and have wanted a family for a while. We'd had a few fertility issues (I have PCOS) so it's been around a year of trying with no success but he is now getting cold feet after we bought home our rescue dog 3 months ago who has some behavioural issues (dog aggressive).
I've had some anxiety about walking the dog and he now doesn't think i am ready for a baby. He said that we need to get the dog's issues under control and for my worrying to stop before we should start trying again, however that might take months or even years! I am already 30, if the dog never gets better and i am still worried about walking her that could be another 10 years and then we'd never have kids!
I'm at a loss of what to do, how to approach it, what to say to him. He just thinks I am baby-mad and don't see the bigger picture, but i tell him that there's not 'right time' to get pregnant and we'll just deal with it as we have every other challenge we've faced so far.

TL;DR Husband now doesn't want kids due to dog causing me anxiety.

Thanks so much everyone for all of your advice and suggestions. To clarify a few things

1 - we are currently working with a certified behaviourist, however seen little improvement in the 2 months we've been having sessions. She is only aggressive to some other dogs while on the lead, so our only concern is her walks. I know it 'might' be possible for her to recover but it's the chance that she won't that is worrying - am i expecting too much too soon?
2 - In terms of other problems, we live 300 miles from our families and recently our best friends have basically disowned us so we're a little on our own. We'd talked about bringing up our kids together but now they won't even return our calls. I think this might have something to do with it.
3 - I trust him 100% and honestly do believe he does want kids, he just doesn't think this is the right time. We've been together since we were 18.

It doesn't help that i'm not 100% happy in my job but it has great pay and good benefits, i was staying in the job because it was a means-to-an-end (Mat Leave) but if that isn't going to happen for another 3/4/5 years then what's the point? I might as well find something new and start over.

the last thing you want to do is bring a baby into the world with a father who doesn’t want him or her, a mum who is emotionally fragile and an aggressive dog in the house.

Lolly, this really hit home. Thank you for being frank. I guess i need to take a step back and actually assess the situation more subjectively. Something that's quite hard society (and our fertility doctor) has slapped a great big ticking clock on my womb!
