Rescue dogs - PUPPY

I think it will depend which 'rescue' you are using: there are breed rescues and local rescues and broadly national organisations such as The Dogs Trust, and they will all have their own standards and requirements.

I'd hope that any organisation would check your suitability to take on a dog, and particularly as you want a puppy, given that a puppy is a far bigger commitment than a dog. There may also be a much longer wait for a puppy.

A rescue dog is likely to come with vaccinations, micro chip already in place, as well as, maybe, housetrained, some basic training and being used to being in a house, left alone...... a whole lot of bonuses. They probably will come some/ a lot cheaper as you will be contributing to the running of a rescue centre rather than (possibly) the profit of a breeder.
Sometimes puppies come into rescue.

Much as I would love a puppy they are a HUGE amount of work. At the start you need to be with them all the time so you can put them outside every hour or so. Puppies do not bring up themselves!!

I have had my most recent rescue dogs at age:- 3 @ 2year olds, and 1 @ 14 months. The last was an awkward teenager, the other 3 were still very lively but not hard work and they became house trained within a couple of months.

Have fun
