My boyfriend and I have a pomeranian 9 months and when she was 3 months she met another puppy the same age (Maltipoo), we became friends with the couple raising the MP. We'd often go on walks together, or cafes and restaurants. (I feel like i need to include this information, but it was always us who paid, they paid maybe twice? We also planned a trip to my home country at the end of the year to run a half marathon and my boyfriend offered to cover the plane tickets and they accepted without hesitation). We built a nice community together and our dogs were apart of this dog walking group thatll meet and allow their dogs to play together. Everything was fine but once the MP hit around 6 months, he would play extremely rough with others, not in an aggressive way, but you can tell the dog had alot of pent up energy. (The MP owners didnt exercise him and he is inside alone all day of their apartment that is very small) it was known very quickly the MP was too rough with the other dogs and the owners didn't like it. He was very often too rough with my pom, dragging her by the hood of her clothes if she had it or the fur of her tail, she'd run to me for help or I would have to pick her up and stop him from "playing" with her. The MP owners also very often stopped him and complained he is too rough with her. I meantioned i was concerned that he will break her back because he is significantly stronger and larger than her. They would often say how jealous they are that i have such a calm dog who listens to me, and I'd have to mention it's because she is exercised regularly and I trained her. I stop going for walks at the time they went for walks because I was worried about my pom. The day came where they walked their dog at the same time as mine and when they greeted eachother the Mp owner let lose of his leash, instantly wrestled my pomeranian to the ground and we just heard this loud scream. My poms back leg was injured and she was in so much pain, while I was checking the damage they were commenting on how my pom is just a princess and dramatic. I told them that she's been hurt and I taking her to the vet. At the vet they took xrays and told me my pom has a dislocated knee cap, (this is a common injury in poms that can me naturally occurring but before this day, my dog had a health check up and she showed no signs of a Luxating Patella) The vet confirmed it was most likely caused by trauma. And told me monitor her and if she's not better then she'll need surgery cause if not fixed it can cause her more health problems in the long run. I told the MP parents and they started blaming her breed, they asked me what should be done about the vet bill and I said once I know for sure if she needs surgery we can discuss all the expenses together. For 2 days they would ask me or my bf how is our day, not once did they apologize. Instead they tried to convince us that the fault was not their dog and blaming the breed. I told them that yes pomeranians are know for weak legs but she had no prior injuries and was extremely healthy before this day and the fact of the matter is she was injured due to rough play. Its always as if once they realised that I wasn't going to change my reasoning for her injury, they stopped all contact. This happened 2 weeks ago, I went to the vet yesterday to see if she needs surgery and he confirmed he does. When i told the MP parents what the vet said and what the cost was and i made a suggestion on a payment plan, they told me that it is not fair that I ask them to pay anything and they have been speaking to other dog owners and because their dog didn't bite her they shouldn't need to pay. I mentioned to them that their dog is the reason my dog got the injury, and i said if roles were reversed i would do anything to help them, even if I couldn't afford the vet bill I would not ghost them and offer to help in his healing process. They then carry on to say that my dog was just lying down and she dislocated her knee when she got up. I reminded them again that their dog is very rough. They refused to admit that their dog played rough at all. I told them im not demanding them to pay, but as respect to each other, it should be common knowledge, they then went on to tell me i have embarrassed them by presenting the vet bill and pointing out their dog caused the inury???? They wanted to give 5% of the surgery cost but i said it was an insulting amount. I tried so hard to remain composed and diplomatic.

When i took my pom for a stroll in her stroller cause she can't walk. I saw the dog group and I greeted them and they started bombarding me saying I'm not being fair making the MP owners pay for something that is not their fault and when i asked them what they knew; apparently the MP owners told everyone that my dog injured herself while getting up from lying down and blamed me for being a foringer (which.. how?)

I feel like this is unnecessary and they are taking it as an attack on their egos. Many people i spoke to said that if their dog injured another dog, no matter if it was a bite or rough play then they would pay or help. So AITA
