In my opinion, the aggressive dog is dealing with some insecurity issues. You said something happened recently at the groomers? Does the aggressive dog dislike going to the groomers? While I agree that a trainer can help, sometimes we cannot financially afford this option. I would definately take the dog to the vet and rule out any physical problems first. Also, are both dogs neutered? This can SOMETIMES improve their behavior, although it can take up to a couple months for them to calm down, and it doesn't always help. There is also the possiblity that there is a female dog in heat somewhere within your vicinity. This always makes an unneutered male become more aggressive with other males and even females. There are so many reasons this could be happening, you most likely will have to rule them out 1 by 1. If your looking for good reading material, check out books by Cesar Milan. I firmly agree with his training methods and understanding of dog behavior. Definately, watch the two of them when they are together, and whoever told you to let them work it out by themselves? In my experience of over 25 years of living with dogs, It will only get worse if allowed to keep going on, and that's something I wouldn't want with a new baby on the way. |
