Out of 11 dogs over the years, only 2 were chosen/bought as pedigree puppies all my others have been adopted either thru one rescue or privately ( 3 from the same lady )
3 from the rescue I fostered first, they fitted in so well with the current dogs I had at the time that I adopted each of them ( not all at once but one by one )
Some of the rescues have been x breeders from puppy farms, so my home was the 1st home they had ever been in, they took great comfort from being with other dogs.
My rescues have varied in age from 1 year old up to 7 years old. One of the 7 year olds recently passed at the good age of 18.5.
Every single one became cat friendly despite not having lived with cats before, I have and always have had cats, had the cats first.
The rescues/adopted ones have been a variety: labradors / beagle / bichons / shih tzu / pug / pug x shih tzu.
Lead walking / toilet training was not difficult as each would copy / learn from the resident dogs, they are grass / sand trained i.e. very very very rare will any of them ever go toilet on concrete / gravel they wait until they reach grass / sand ( we live near beaches so they see a lot of the beach. )
Health wise 2 from the rescue had little issues, one had had cataracts removed and was on eye drops for life, and another had dry eye so was also on eye drops for life.
Neediness - two of the private rescues are kind of needy / clingy, I am very loved :) I always have a dog on my knee. I am never cold.
How they will cope when there is only one of them left one day will remain to be seen, but I expect to be retired by then ( 2 years to go ) and I hope they live until double figures, they are 7 & 8 right now.
