They have a beagle. A very loud, male beagle who barks incessantly multiple times a day. They have previously told me that there will be some barking while they crate/sleep train but it's been going on for 6 months now.
I don't expect perfection. But I don't expect to feel angry in my own house.
I'm 99% sure their lease doesn't allow for pets either which I find irritating. Presumably for the issue of noise affecting neighbours!
(We own and are leaseholders, our headlease does not allow for pets and I'm 99% sure their landlord's headlease is the same as it's the same freeholder as ours).
