Our Dog gets suddenly attacked at Dog Park OMG😭

Life with our Belgian Malinois American Akita Our Dog gets suddenly attacked at Dog Park OMG😭 I’ve had a look and it looks real nasty . so will wait for his dad to get home and see if he needs the vet . I have tried to bathe it, but he keeps running off. don’t let your dog socialise with smaller dogs . I think they find him a threat as he’s so big . but he is only a pup and very friendly . I hope this 8 year old nasty Spaniel attack hasn’t damaged him and made him reactive as he is beautiful with other dogs. This is the third Dog that’s attacked him out of the blue. I feel I have let him down by letting him greet it . grrrr tut sigh sobs I hope he won’t have a scar 😔 mortified for him 😢 We was having a really nice lovely happy walk too until this and he’s been doing some agility training. il upload it .
