Pet's info: Dog | Havanese | Female | 5 years and 7 months old | 19 lbs
Our Havanese is a rescue which we have had for a year. She is afraid and goes ballistic whenever she encounters other dogs. We have had her to dog trainers and nothing seems to stop her from pulling and barking.

Hi there! Aggression issues in dogs can be really frustrating. One of my dogs sounds pretty similar to Sammi, so I sympathize. Many dogs that are showing signs of aggression are truly anxious and unable to control their emotions. Anti-depressants and anti-anxiety medications can be used both long and short term to help them learn to process their emotions while in a calmer state. Commonly used drugs for this purpose are Prozac, Trazodone, and Gabapentin. I would recommend calling your vet and asking if they see behavior consultations or if they have any recommendations for a board certified veterinary behaviorist (someone who goes to three more years of school after vet school just to study behavior). I would also encourage you to use only trainers that focus on positive reinforcement learning. Fear tactic training can make aggressive dogs much worse. A good trainer can talk to you about helping your dog learn to focus on you during stressful situations and better their impulse control, to minimize these situations in the future. I hope this helps! Thanks for using Petco Pet Education Center, formerly Petcoach!
