So i was walking my boy (leashed) in a park, when a LEASH-LESS, LICENSE-LESS, TAG-LESS, OWNER-LESS full grown mastiff comes charging at me at full speed. He had nothing but a SHOCK COLLAR on. and he lunged at me. I swear i saw my life flash before my eyes. He must have been at least 95 lbs and over a year old, he looked fully grown. Cairo, seeing that i got knocked off my feet used his 48lbs of muscle went and tried to help me out and got into a fight with the mastiff, when i regained my balance, i pulled my boy off of the mastiff, even though i wanted to stab him with my knife that i keep in my sock, and as i looked for the owner, who was standing about 50 feet away under a tree, DOING NOTHING BUT calling for his stupid dog "FAVRE" and shocking the dog with the shock collar. if i wasnt worried about our breed and the fight that broke out between the two dogs i would have gotten into a fight myself with this lazy, undeserving head. WHO THE HELL has nothing but a shock collar on their dog, not only do I FIND IT inhumane (IMO) but APPARENTLY, it does NOTHING to a dog whose body weight is about the size of a teenage boy. Ive been so mad all day, and i just found out a couple hours ago that my boy is limping with what i think is a sprained back leg... is there anything i can do about it, a type of pain meds i can give him, cant go to the vet, because i dont ahve the money for it right now, and frankly, its not too bad that i want to waste a trip, but in the mean time, he looks like he's hurting a little bit. I feel bad i couldnt do anything... any suggestions??
