I already have an old entire male dog. He is good with our cats and rabbits, and good with my parents dogs (despite one being very grumpy with him). But he is very soft and can be anxious, so after being attacked a few times on walks, he can be a little reactive on lead. I think the fact that he is entire, plus his puppy like ears make him a bit confusing for other dogs. Having said that, he went to the vet hospital yesterday and was very well behaved in a waiting room with several dogs.
We want to introduce a puppy into the house. I'm not sure whether a bitch or a dog would be best? A bitch might be better because mixed sex dogs are less likely to be in competition, but as our existing dog is entire, we'd have to spay before the first season, or keep them entirely separate for 3 weeks, or give our existing dog the chemical castration implant. If we get a dog, we'd have to neuter early or hope they didn't get competitive, or give the older dog the chemical castration implant.
When we got our existing dog from the rescue, they didn't recommend castration because he has a very soft temperament and they felt he could do with the testosterone.
Does anyone here have more than one medium/large breed dog? Do you have same sex or mixed sexes?
