unfortunately i think it varies from area to area & manager.
i used to have a 'freind' who managed to adopt to dogs trust dogs, despite working full time & having a very unsecure garden- she simply lied!

both dogs had flea allergies which werent kept under control by her,
she then decided to get another (young) dog in case either of the other older dogs died!- all bitches- unsurprisingly they fought, the young dog bullied the older two, wasnt house trained & all 3 were very unhappy:(- no training stimulation, or exercise done- just shouting at the dogs for behaviour 2 seconds ago they found funny & laughed at

she THEN got another young dog to keep the other young dog company- an almighty fight broke out resulting in two injured dogs & she then tried to privately advertise one of the older dogs for sale.
this sad situation was only resolved after i informed the dogs trust & resulted in the end of the 'freindship'
i have to say i did try & help & advise her, but she would not listen:rolleyes:
she was one of those people that thought lots of pets= pet lover.
& the fact that ahe 'rescued' them made her an even more ' caring' person
