Can an old dog get depressed and stop eating when a new puppy arrives?

Updated On September 23rd, 2025

My daughter’s labrador cross, 14 years had to be put down. In fine fettle, splayed, a little deaf (more independent?) she stopped eating, caught pnemonia and although recovered was so weak she had to be put down. Could she have had a ‘depression’? It started soon after they took in a puppy of 2 months. She lived with two cats and had tolerated arrival my Parson Russell, male, 4 years - who she promptly disciplined!

Fourteen is a good old age for a Labrador. Often they seem fine but they are frail and aren’t able to fight off infections like a young dog, and if she had trouble with her legs the lack of exercise may also have contributed. While she may not have enjoyed the new dog that shouldn’t have caused her illness unless it gave her the cold that became pneumonia.
