50 Unfortunate Animals Whose Day Didn’t Go Exactly As They Planned (New Pics)

Rollpet adds that disinterest in other pets also qualifies as a possible sign of depression. Sometimes, pets can lose interest in playing with other pets that they've always had fun with. If they start biting or scratching their play partner, that's a sign they don't feel comfortable around them for some reason. Experts advise not to push your pet and give them time to adjust.

It can be hard to read a pet's facial expression as they don't use their facial muscles the way we humans do. However, there are still ways to tell a pet is feeling bad just by observing their body language.

Fingers And Paws Dog Training lists some signs that a dog might be feeling off. And they say it's important not to test their limits and give them some space if they're exhibiting this behavior.

Alarming body language can include rounded and worried-looking eyes. If their ears are angled sideways or back and down, that's also a sign that the dog feels anxious. Their tails can also tell a lot about how they're feeling. It shouldn't be lower than usual, and the wag should be sweeping and loose.

Sometimes, pets might want to make themselves look smaller – that's also one sign of anxiety. Unnatural crouching with a lowered head and rounded back can signal that a pet is worried about something.

However, try not to jump to conclusions. All these signals by themselves might signify nothing. Context matters – always look at the bigger picture. If the pet isn't eating, wants more quiet time than usual, and avoids eye contact with the owner, that might indicate an anxiety or depression problem. Remember – it's always better to consult with a vet than try to diagnose your furry friend yourself.
