Senior Dog Mix Portrait with great dane litter size

Imagined hybrid dog cross-breed with approximately 50% trait influence from a Dachshund and % trait influence from a Golden Retriever, senior stage. Realistic anatomy that visibly weighs the dominant parent more heavily — coat colour, ear shape, snout length, body proportions and tail should reflect this 50/ split. Coat tendency: natural blend. Style: outdoor natural, environment: cosy living room. Single dog only, friendly relaxed expression, healthy well-groomed appearance, soft natural lighting, sharp focus, photo-real rendering of fur texture. No animal cruelty, no injury, no aggression, no blood, no humans, no surgical or distressing scenes. A single dog only. Specifically: cocker beagle.
