Why is my unspayed dog suddenly aggressive and hiding with toys?

Updated On September 23rd, 2025

Pet's info: Dog | Catahoula Leopard Dog | Female | unspayed | 5 years and 6 months old | 66 lbs

Hi, my dog has all of a sudden become aggressive over a toy, shes a 5 year old catahoula. It started 3 days ago. She would hide under a big plant and only come out for food. She took all her toys to the hole under the plant and whimper and lay on them. She came out today and lay in a cubby house with this one ball. If I go near her she nudges the ball and growls till I go away. Yesterday and this morning she came out and was happy for a cuddle but now she won't come out. Any ideas?

Hi. Thanks for using PetCoach. Since she is not spayed my best guess is that she is having a false pregnancy. If you are not planning on breeding her my recommendation would be to get her spayed. ( https://vcahospitals.com/know-your-pet/false-pregnancy-or-pseudopregnancy-in-dogs ) Best wishes.
