My dog is almost 13 years old, she's been a great family dog and we all love her (especially the kids)
Last year or so she's really changed, suddenly seems very old, has a lot of lumps and bumps, doesn't enjoy walks as much as she used to - is very slow. She often walks around the house aimlessly, she'll stare at walls and cry or sit in the middle of the garden and cry. She seems ravenous and will cry for more food when she's already eaten, she's looking thin despite this. She's also gone to the toilet in the house a few times overnight (something she never does) Her eyes also look like she could be losing her sight. Up until recently I've thought she's just getting old but seems ok in her self most of the time, will still cuddle up with the kids etc.
Last week she randomly attacked our cat (who she's lived with since she was a puppy) he was ok luckily but we were all shook up, can't see a reason for it - he wasn't anywhere near her or her food or anything like that.
Tonight she randomly snapped at my hand when I bent down to pick a tea towel off the floor. It really shocked me.
Up until now I've been reluctant to see a vet because I imagine they'll suggest tests/scans or the like, we live hand to mouth as it is. I'm slightly concerned her behaviour is indicative of cognitive decline.
Part of me thinks if she continues to decline it might be the kinder (and safer) thing to have her put down.
What would you do?
