We lost our 12yo rescue male border cross in September. Our other dog, a 7yo terrier cross we've had since a puppy, always got on well with him until the last few months when she distanced herself from him, and occasionally would snap at him asserting herself. Since he died, she's become more confident, friendly with people (she was always very shy around people), as a positive, but as a negative is spending a lot of time scavenging and seems a little more unfriendly around other dogs. She's always had her favourite dogs, and is friendly with them, and this is still the same, but she seems snappy and grumpy with younger, bouncy dogs. We had thought about getting another dog, but now I have reservations. Any thoughts whether this could possibly be a grief reaction, or do you think she's actually enjoying being an only dog?!!
