Where we live there are very, very many dogs. Some observations;
There are far too many dogs in the UK. They seem to have become a fashion accessory for many.
Many seem to pay hundreds to buy a dog and then spend well in to an annual 4 figs on the cost of ownership, but then plead poverty.
Poor dog behaviour is 99% down to lack of training and ignorant owners.
I don't have a problem with dogs in shops, or elsewhere, if well.behaved. Indeed, I'd rather the dogs than many of the humans.
Having said the above, we both love dogs! They seem to have an affinity for me and thay all come up to say hello; even the unruly ones settle down when I make a fuss of them. We would like a dog but, for the present, it's not practical and would be unfair on a dog.
