, I have two female Vizslas. My oldest V. Sophie is 2.5 years old, and my little baby Pacsirta is almost 11 months old now. I LOVE having them both, but I will be very honest and say that it is not always easy. Just like you, our Sophie was our first dog, and we had never had experience owning two dogs in the same household. We wanted to have another female, but most research we did on multiple dog households suggested to have opposite sex dogs. Still... we went for another female. The breeder assured our little Pacsirta had a very well-balanced character and would fit in with Sophie very well. Pacsirta was everything I could ever dream of - the sweetest Vizsla girl out there...yet confident with great working dog instincts.
Our Sophie is not a dominant dog at all, and I think it helps a lot because same sex dogs can become competitive, especially bitches (from what I have read and heard). I have observed competitive behavior with my two when it comes to petting and greeting. Little Pacsirta wants to be first! I have to tell her to wait her turn which she patiently does. Plush toys trigger Pacsirta to become more obsessive, and she will not let Sophie to have them. I actually just remove them to avoid the situation. However, if Sophie doesn't want to put up with something Pacsirta is doing, she will definitely tell her. We haven't had any fights between the two but there have been times when teeth have been shown and growls have been exchanged. I find it a normal behavior, it usually last few seconds, and we rarely interfere. It is important though to let them know that we make the rules, and they obey them no matter what.
They eat together, sleep together, play together... they basically spend most of their time together. It is really hard to imagine having only one now... They love to be together and makes us smile every single day
They both have been staying home now while we are at work and have been great at it! I feel like they just sleep most of the day
