The picture below shows socialization/interaction between 2 groups of fostered dogs: on one side we have a litter of pups and on the other side we have 2 rescued adults (Staffordshire Bull Terrier crosses). The 2 adults had not been in contact much with other animals during their life time. Our volunteers made sure a safe distance was kept, but both parties did remarkably well without any barking or aggressive behaviour.
Often people wonder: why do you put the animals in temporary foster homes?
It is actually very logical: when the dog or cat gets put into a foster family, it has exposure to an actual home. This means lots more training can be done, the animal can socialize with humans and other animals, house training can be included, etc.
The results? Our dogs often have a head-start and can easily adjust to living with a new family.
