You may be scuppered regarding rescue centres. When we wanted a dog we approached the local RSPCA branch, and the local BATTERSEA Dogs Home branch. Ds was 5, dd was 2. Both places said they would not rehome a dog to a family with a child under 5. (Once place even said they preferred the youngest child to be 8)
So we ended up getting a Cocker Spaniel puppy. We researched our fave breeds, then approached local breeders and spoke at length about our requirements/circumstance/wishes. Some breeders turned us down as dd was so young.
Finally we found a breeder who after she had met us was happy to put us on a waiting list for a puppy. 4 months later one of her dogs had puppies, and when these were 2 months old we were allowed to choose one. She had earmarked the most laid-back ones from the litter so as to suit our still young dd.
Dillon has now been with us nearly 2 and a half years. He is fantastic. He is a chocolate brown cocker spaniel and looks just like a brown bear. He is currently curled up on the sofa with ds watching tv. He is very bouncy and loves attention (like all spaniels) but his breed is keen to please so relatively easy to train. (Dill does have a lovely stubborn streak though
The novelty has not worn off with the children. Ds is now 8 and dd nearly 5. They take it in turns to feed Dill and brush him. They like running around in the garden with him and throwing a ball for him. Walks in the local woods are great fun, the dc love getting muddy as much as Dill does!
Yes it is hard work, the never ending trail of muddy pawprints, the twigs and leaves he brings in, the half-chewed tennis balls scattered throughout the house, the remnants of chewed up post and newspapers, the non-stop poop scooping both when out and in the garden, the dog hairs in the fridge, on the sofa, on the bed etc.
But it is also lovely. The dc love their dog so much, they have a real bond. I love the fact Dill is always up for a snuggle, and when I am stressed or in a bad mood then taking him for a walk is a sure fire way of making me feel better. I love the way he tries to snuggle under the duvet if I try to have a lie-in (he only attempts this once dh has got out of bed), and he makes us mad with his daft antics, from trying to chase butterflies round the garden to trying to retrieve his tennis ball from under the sofa. It is just like having a clumsy, hairy, 4-legged toddler in the house. Great fun!!
