House Trained Dog Wetting on Dog Bed and Fabric?

I am just after some advice as we are really at a loss as to what to do. We have 2 Yorkie dogs a male and a female they are both coming up to 2 years old, both are neutered. Our female is wetting everywhere in the house, mainly on her beds and fabric. She seems to have regressed loads from where she was with her house training.

When we got her at 8 weeks she was already house trained as she used to go outside in the garden with her mum and siblings. She obviously had some issues with wetting in the house as she was little, but overall she was really good. She even helped our Yorkie boy who we already had but is from a different litter to go outside. I did have to remove rugs as they would both wet on these, but we did use puppy pads. They go for walks and neither have a problem going outside whilst on walks. She was totally and fully house trained.

The problems started after we went on holiday for 2 weeks. We put them into kennels and ever since she has had problems which seem to be behavioural. They have a crate which is always left open and also a bed in our living room. They both share their beds, but both dogs began to really smell of wee and at first we just couldn't figure out what was happening. I suspected she was weeing in the crate it had, at the time, a fleece type padded bottom and I would regularly wash it, but it was difficult to tell as it totally absorbed everything. Anyhow after weeks of this I noticed that when I had been out and came back to the house she refused to go outside and would run to her bed or her crate. I caught her peeing in her crate, but properly just laying there doing it which she now does regularly. I put her outside and from then the fun has begun!

Our male doesn't wet anywhere apart from outside in the garden and he tells you when he wants to go out. I bought them 2 new beds that are waterproof, one for our living room and one for their crate. When put outside she will refuse to go, wait until she is inside and run to her bed and wet no matter how long she is in the garden for and she will bark excessively until you let her in causing our neighbours to complain. If she ever does wet outside she is praised loads. I have even opened the garden door and she will go to run outside. But she will then quickly jump on her living room bed and wee with the garden door wide open. She will jump onto curtains and try and wee on those. It's a total nightmare.

We have spoken to the vets and she has no urine infection or bladder problems and her wee doesn't smell or look infected at all. She will totally refuse to go outside when it's very cold, but will go outside and lay in the sun and sun bathe when it's sunny. She is a little diva haha! A cute one though! I have some anti-enzyme spray and clean their beds regularly and spray that and she also goes on 2 walks a day, but it's still not stopping. She will also wet on the floor when she gets excited at seeing someone so I am thinking could there be a bladder issue and we have just been fobbed off by the vets as it's the same vets that neutered her?

Saying that though she is able to hold it for a good few hours until we arrive home. We are just baffled. Luckily we have hard flooring so anything can be cleaned easily, but we also have kids and a baby on the way and it's not ideal hygiene wise. Out of the two dogs she is the most dominant and barks a lot, but at the same time very submissive towards people, yet also demanding of attention. If the male gets stroked and a fuss, she will jump in front of him every time and want attention. Yet she dominates the male dog and has him wrapped around her little paw. I am totally confused by her and want to get this issue sorted so she is a happier dog
