Most poisoning of dogs is accidental. Garden poisons, such as snail baits, are the main cause. If your dog is known to eat just about anything, then be particularly careful to store poisons where they will not be accessible to him. Dogs found foaming at the mouth, with muscle tremors or staggering gait, or unable to stand, should receive immediate veterinary treatment.
Keep your dog busy by prolonging his mealtime with a number of interactive toys such as Kongs, treatballs, or Bustercubes (treats can be easily pushed in but will engage your dog for hours trying to get them out). Also try hiding part of his meal around the yard to stimulate his natural foraging instincts. Treats and toys are available at the RSPCA online shop.
It is important to note however that dogs who are never, or seldom allowed indoors, are more likely to become bored - and as a result become disruptive (e.g. bark for attention) and/or destructive (e.g. dig up your newly- planted rose bush). This is because dogs associate their human family as their pack and can develop behavioural issues if they feel neglected as a consequence of being excluded from interacting with their pack.
Giardia intestinalis and Giardia duodenalis are single celled protozoan parasites, which inhabit the affected dog’s small intestine, causing clinical signs of Gardiasis. The protozoa attach themselves to the intestines and multiply. They may be directly swept through the intestines and appear in the infected dog’s faeces or they may develop into a tougher more durable ‘cyst’ form, which is again passed in the dogs faeces but is able to survive for long periods in the external environment. Dogs are infected by ingesting the cysts from contaminated water and the environment. Infected dogs may not show any clinical signs of Gardiasis, but they can still shed the protozoa from their systems, spreading the infection to other healthy animals. Infection and subsequent illness is more commonly seen in younger animals. Signs of infection include: chronic or intermittent diarrhoea that may appear ‘fatty’ and slimy, accompanied by a very foul smell. Weight loss is also possible if left untreated.
