We adopted our rescue dog from Portugal and I agree that it’s important to check that it’s a reputable shelter/ charity. We actually visited the shelter in person and spent some time with our dog before we adopted him so had a bit of a sense of his personality/ the environment he was coming from. Obviously not realistic for everyone to see the shelter/ dog in person before adopting but personally I don’t know if I would have taken the plunge without doing that.
I would pay close attention to the shelter’s vetting checks of you as well. I think a good shelter will ask you as many questions as you ask them. We had to give lots of details about our set up, how long dog would be left alone for, what would happen if we weren’t happy with his behaviour, etc. They also got someone to come and do a home visit with us to check that the environment was suitable. After our rescue arrived with us, the shelter continued to check in to see how he was getting on.
In terms of questions I asked them - I clarified things like any known behavioural issues, medical issues, what vaccines he’d had, whether he had any training and if they knew what his background was before he came to the shelter.
Our rescue was dumped at the shelter as a really young puppy and so had never been in a house before, which meant we had to house train him for example so it was good to be prepared for that.
I second what some others have said about behaviours coming out over time. The first week or so he was on his best behaviour and just slept at my feet! But once he settled in he was a bit of a terror for a while - he was also going through his adolescent phase and wanted to rebel, which didn’t help matters.
So be prepared to pay for one to one sessions with a good dog behaviourist and putting in lots of time for training. Be prepared for regressions in behaviour as well. For example, ours went through a play biting phase a few months after we got him and a few weeks ago starting doing it again, so it’s like one step forward two steps back sometimes.
I think my top tip is to manage your expectations and think through worst
case scenarios. Like what would happen if the dog suddenly developed a medical issue that was going to cost £££ to fix. Or what if he couldn’t be left alone for more than an hour or so at a time? There are some issues that all the money, training, time, etc in the world won’t totally fix so it’s about thinking through what you could cope with, what your red lines are, and trying to ask questions of the shelter that will flag up whether you’re likely to have those issues and what support they would provide in those scenarios.
