I really, really have to agree with everything posted by CorianderStreet above?
We know at least two families who have, of course utterly inadvertently, bought from puppy farms with concomitant distress and heartbreak for the family and terrifyingly huge vet bills while propping up a truly disgusting industry. Our school gate last term was suddenly full of dozens of cute yapping bundles of lockdown fur, some of which had been collected at motorway service stations, obtained via mobile telephone numbers on Gumtree and various other well known - and easily researchable - scams?
Please talk to all your friends who already have dogs and ask tons of questions about the breeds that seem to appeal most to your children and to yourselves? Many people feel the popular mixed breeds such as cavapoos etc., provide healthier dogs but there is actually no strong evidence for this; fashion seems to be the rather more persuasive factor?
Personally I would always go for a single breed but that is because we love our elderly springer and silly young working cocker spaniels so very much! I am sure a few people reading will say that you should get a rescue, However, there is also a long waiting list for these atm and, given the ages of your kids, you would generally be far safer with a puppy which can be a cherished member of your family from the very start of its life?
A dog will bring unmitigated joy to your family. You simply cannot imagine quite how much until this hugely anticipated family member arrives. However, please don't underestimate how much input there will be, whether or not you are WFH? The three months immediately after they arrive, when they need to be very gently, slowly and carefully socialised - both with other dogs and people in general - are absolutely crucial and one careless mistake can affect the dog's character and health for the rest of its life - as we know from bitter experience? Clearly most dogs - and crucially, owners - in our area are prudent, well-behaved and reliable but sadly, you always need to remain vigilant in all of our local parks and commons, particularly now they are currently so crowded?
Again, Kennel Club, Battersea, PDSA all have good puppy/dog buying guides. We really like this one from the National Animal Welfare Trust and its section on 'Questions to ask the breeder before you go and visit' is spot on? Good luck! Be patient? Don't forget, you don't find the dog - the dog always finds you! Warm best - Dee
