Just to torture myself... and show my empathy for your situation... I'm gonna post the dogs and pups that were the closest to being permanent... the thing is... if any of them had stayed, the subsequent dogs would not have been.
Last weekend Bubba went on a trial overnight and it was the first time in over two months that my Arlo let his guard down enough to snore away in the front room in the middle of all other activities... that type of stress that I put my dogs under reinforces when I know I have to hold that boundary to two dogs. At this point I focus on fostering for the AC or other groups where I know I am doing good but it is for a set time period and I have an outlet...
Really...almost had to keep her: (a cruelty case form the AC her owners poured acid on her then withheld medical care) Butterfly:
Bunny and Blondie: my first AC fosters and almost had to keep the darker one:
Thsi guy got placed thru AC and went on to die of a bowel obstruction (worms) less than a week later. Despite deworming him 4 times, inadequate vet care suggested PTS. We still mourn this one: Monkey
picked these guys up via Criagslist "free to good home" Made about 10 trips to vaccinate and de-worm them, got them s/n and into another group to re-home 'em. No danger of keeping any.
Most recently, a neighbor handed me the black/brindle one at 5 wks old. I sniffed him out another litter in rescue to join to ensure adequate socialization...Only prob. was the other rescuer couldn't prevent the pups owner from handing them out intact and free at 6 weeks so...needless to say, this photo is titled "My Ex-Kitchen" Seriously, anything that was not bolted down was in the living room.
I guess what I'm trying to say is, I understand. At the end of the day you have to do what is right for you, your family, your dogs, and the dogs that are yet to cross your path.
Warm regards, M
