Borrow a friend’s dog first. Let them have a holiday :)
Failing that, try to avoid taking on a dog from a bleeding heart, rehoming charity where you don’t meet the dog. If it’s easy to adopt the dog, either the checks on you aren’t sufficient or that they don’t know the dog’s needs.
Meet Fen. From the mean streets of Moscow brought over by 2 Russians in a knackered Opel van with 15 other dogs 3 years ago. I couldn’t believe it when I saw the van full of dogs.
She’s very friendly and playful, but an utter coward (scared of ducks, the dishwasher, bichon frisé, creaky doors and old women). The charity advertised the playful side, but did not explain (or know about) her timid nature. We were lucky that she’s a gentle soul and easy to train, unbeknownst to the charity.
