Are Standard Schnauzers good with other dogs?
Yes, Standard Schnauzers can be good with other dogs, but this depends on several factors, including their early socialization, training, life experiences, and individual temperament. 
Because this breed can be prone to being dog-selective, it’s important that Standard Schnauzers are well-socialized from a young age. Early and frequent positive experiences with a variety of dogs in different settings can help them develop healthy interactions. Since they are energetic and playful, they can make excellent companions for other dogs with similar energy levels. 
Standard Schnauzers can be territorial, so early socialization with other dogs should include their home environment. This will help them feel comfortable accepting other dogs in their space.
Realistic expectations can help you adjust if your Schnauzer is struggling to be a social butterfly with other dogs. While early socialization can significantly help your dog to feel comfortable with other pups, many dogs remain dog-selective throughout their lives, and a good goal to set is to help them remain calm and feel safe around other canines, even if they aren’t highly social.
