Thanks guys!
Were home now and she is ok.
Was HORRIBLE,I've empathised hugely when I've heard about peoples dog's fighting/getting hurt but I don't think you can ever be prepared for that.
Basically we were walking in the park,Coco was off-leash and we were approaching a couple with two children and three dogs.One of the dogs was on a leash and two were running loose.I automatically asked Coco to heel as she can sometimes be reactive to children on scooters. As we approached the man called out to his dog "No...lillly stay back" I did'nt get anything from that though tbh and he didn't warn me. I continued walking and when I turn around the dog had her by the neck.I don't know how long it lasted but noone had a CLUE how to get the dog off coco,the man was pulling his dog and holding her up Coco was getting thrown all over the place,he almost had coco pinned down under his legs while he tried to pull. I have to at this point give kudos to the stranger who even attempted to put his finger up the dogs bum . But that didnt work. I don't know how but i think I got the dog off Coco I was trying so hard not to have a panic attack.
Anyway the wife told her husband to "LEAVE" the park and she walked me to her house,I managed to get my sister and mum to come over and then the lady drove me to her 24 hour vets with my sister. Luckily for me she was very helpful,she paid the £650 in full and arranged a taxi for me to go home in.Coco has been stitched up and given meds.
We are finally home tucked up safe.
Thanks for the vibes,if anyone has any advice as too what they would do next that would be great. I'm very worried she will now become fearful/aggressive with other dogs? Also am terrified of what could happen if the dog had been bigger,so what do I do?Stop walking her in the park/off-leash?
