Hi, it is never too late add a puppy or another dog in my opinion.
If you can afford the vet bills and future vet bills as they age, I say go for it.
Remember that you only have two hands but the good thing is that you can tie all the leashes together when you walk them. I had 3 dogs for years with usually two foster dogs. When I wanted them to come to me, it was much easier just to call "DOGS!"
If you want to carry your dogs three might fit in to a dog stroller. I know you can buy different sizes. I like to take Mya everywhere. My 13 yr old Pom is only interested in trips to the park or going to the cottage. He sleeps 18 hours a day so he is not jealous that I take Mya out in her carry bag. I would imagine it would be hard to go shopping with three tiny dogs with out a stroller. Besides, I find the bags weigh more than the dog *grin* |
