My dog is driving me absolutely mad!

That’s already part of the problem right there. You don’t necessarily need to turn him into a circus dog, but he does need a basic level of training. This needs to be maintained with frequent work on his commands so he doesn’t forget them, and he’s definitely going to need a lot more activity. Vero’s suggestions for letting him burn off some energy are great, especially since he’s fully grown now. However, regarding the Easy Walk harness that was suggested—if he’s anything like my dog, he’ll quickly work out how to slip out of it to do as he pleases. Plus, a front-clip harness (like the Animalin brand) seems more practical for everyday use.

In short, he needs more company and more walks so he can explore and blow off steam. And since you seem to be struggling, some dog training sessions with a pro are a must (Coahoma’s sister is a trainer and did a brilliant job with a dog I saw, but she’s based over in Seine-et-Marne, so it’s up to you whether the distance would be an issue). Given the situation you’re in, these sessions are necessary even if they do come at a cost, because you’re clearly at your wits’ end.

To stop him pulling so much, get him an "Easy Walk" harness – have a look online, the results are amazing :)

His behaviour suggests he’s not getting enough exercise, stimulation, or training... The fact he’s having accidents everywhere shows he’s anxious when you aren’t there, and when he does it right in front of you, it’s either to get attention or because he hasn't quite grasped that he’s supposed to go outside... At night, have him sleep in a closed room, the kitchen for example, so that if he gets up to any mischief, it’s limited to just one room. You need to take him out for at least an hour a day to see any real improvement in his behaviour...

Titain: He’s been brought up like a baby :(

Vero78280: Regarding the separation anxiety, I’ve tried chews and those toys you put treats inside... he won’t even touch them.

It sounds like your dog is lacking some basic training, given that he pulls on the lead, barks at other dogs and has no recall.

What's more, he seems to be suffering from separation anxiety and a lack of stimulation; he’s constantly under your feet, and when you’re not there, he scratches at the door.

A patio is no substitute for proper walks! A dog, especially one like yours, needs to be able to let off steam outdoors!

You’re wondering why you have to put up with all this, but unfortunately, you are responsible for this situation!

A session with a behaviourist costs around £85 at the very most, which doesn't strike me as being that excessive. In the meantime, take him for long walks, try some bikejoring...

At first glance, I’d say the issue is your current lack of availability, as well as his need to explore and burn off some energy (Podencos are a hunting breed and run a lot, so they really need to blow off steam). Between your studies and work, there probably isn't much time left for him, so he’s likely bored.

Plus, you mentioned you didn't really think it through, but spur-of-the-moment decisions are usually the hardest to live with, especially when they involve a 15-year commitment. How have you trained him? Like a baby or a dog? Right now, I get the impression he’s the baby of the house, but a baby who's ruling the roost.
