Asking for a good friend who’s not on here...
He has a 7 year old boxer. Always been a very placid gentle boy.
Around 3 weeks ago he suddenly started drinking lots and lots of water, became quiet and listless, and slight loss of appetite.
Vets did blood tests, everything came back clear.
Now in the past 2 weeks he’s snapped at 2 different people, yesterday he lunged over a metre and caught someone on their face. It punctured the skin but won’t need stitches etc so seems to be a snap from fear, not a proper attack.
Has anyone else every come across this in a dog?
We wonder if it’s something like a brain growth...
The next step is an MRI which my friend is going to save for and in the meantime totally isolate the dog from anyone (obviously easy at the moment).
The worry is being such a large dog, he could do so much damage. He’s not shown any warning signs before the attacks, no triggers, otherwise is his usual soft self so it’s completely unpredictable.
Does anyone have any thoughts or experience that we might have missed?
